It only takes a minute to sign up. I recently upgraded from an ancient Ubuntu installation to Everything works well except for one thing. I can't get HDMI sound to work. I have tried pretty much all sound issue fixes I have found, but so far the sound issue persists:.

EDIT: I also posted this question on I later ran pulseaudio with higher logging verbosity.

You can find the log here Here's what I did: I started the daemon I tried increasing and decreasing the volume. I expect the little pop sound everytime i change the volume, but there is no sound.

I then start spotify and start playing a song, but still no sound I then open alsamixer, select the HDMI card, and I mute and unmute the sound Now there is all of a sudden sound I increase and decrease the volume again, but this time there is sound I then pause the song in spotify and wait for a while When i start playing the song again there is no sound again I kill the daemon I am using HDMI card 0 device 3.

I am not plugging in any other sound cables. WinEunuuchs2Unix Ha thanks. It's a bit on a confusing issue so I felt I had to capture it properly to not confuse people further Active Oldest Votes.

Actually I finally solved this. It turned out to be pulseaudio was using the wrong sample rate. Following the advice in tom. I've been struggling with this exact issue for months!

It also offers easy network streaming across local devices using Avahi if enabled. While its main purpose is to ease audio configuration, its modular design allows more advanced users to configure the daemon precisely to best suit their needs. Install the pulseaudio package. Some PulseAudio modules are not included in the main package and must be installed separately if needed:.

By default, PulseAudio is configured to automatically detect all sound cards and manage them. It takes control of all detected ALSA devices and redirects all audio streams to itself, making the PulseAudio daemon the central configuration point. The daemon should work mostly out of the box, only requiring a few minor tweaks. While PulseAudio usually runs fine out of the box and requires only minimal configuration, advanced users can change almost every aspect of the daemon by either altering the default configuration file to disable modules or writing your own from scratch.

The daemon by itself does nothing without its modules except to provide an API and host dynamically loaded modules. The audio routing and processing tasks are all handled by various modules, including PulseAudio's native protocol itself provided by module-native-protocol-unix. Clients reach the server through one of many protocol modules that will accept audio from external sources, route it through PulseAudio and eventually have it go out through a final other module.

The output module does not have to be an actual sound output: it can dump the stream into a file, stream it to a broadcasting server such as Icecastor even just discard it. You can find a detailed list of all available modules at Pulseaudio Loadable Modules.

This is the main configuration file to configure the daemon itself. It defines base settings like the default sample rates used by modules, resampling methods, realtime scheduling and various other settings related to the server process. These can not be changed at runtime without restarting the PulseAudio daemon. The defaults are sensible for most users, see the pulse-daemon. Boolean options accepts any of these: trueyeson and 1 as well as falsenooff and 0.

This file is a startup script and is used to configure modules. This will make the daemon load the CLI module and will accept the configuration directly from the command line, and output resulting information or error messages on the same terminal. This can be useful when debugging the daemon or just to test various modules before setting them permanently on disk.

The manual page is quite self-explanatory, consult pulse-cli-syntax 5 for the details of the syntax. This is the configuration file read by every PulseAudio client application. It is used to configure runtime options for individual clients. It can be used to set and configure the default sink and source statically as well as allowing or disallowing clients to automatically start the server if not currently running. All modifications will immediately be applied. Once your new settings have been tested and meet your needs, edit the default.

It is important to understand that the "sources" processes, capture devices and "sinks" sound cards, servers, other processes accessible and selectable through PulseAudio depend upon the current hardware "Profile" selected.

Each audio "Card", which are those devices listed by the command aplay -lor again by the command pacmd list-cardswill have its own selectable "Profile". When a "Profile" has been selected, the then available "sources" and "sinks" can be seen by using the commands pacmd list-sources and pacmd list-sinks. Note that the "index" of the available sources and sinks will change each time a card profile is changed. Often, these Flash players will only work when one of the Stereo profiles is selected, and otherwise, will play video with no sound, or will simply "crash".

When all else fails, you might try selecting a different profile. Of course, when configuring some variation of Surround Sound in PulseAudio, the appropriate Surround profile will have to be selected, before Surround Sound will work, or in order to do things like remap the speaker channels. PulseAudio on Arch has pulseaudio.This page goes into detail on using PulseAudio on Linux systems.

It also allows Kodi playback of video or audio to be paused in order to run a game, Skype or similar. Kodi is set to only use PulseAudio if you have installed it and running.

In the past users have experienced problems with audio not working within Kodi, because they were running a full-blown Ubuntu desktop environment with PulseAudio installed. This happened because PulseAudio blocked the device Kodi required, and audio playback only worked reliably when using the virtual Pulse device.

Our workaround for those users has been to uninstall PulseAudio which completely broke desktop audio. As Pulseaudio will always open the number of channels you have configured. If you want to output to all your attached devices in parallel, e. Therefore you need to tell pulseaudio to use a better resampler in general and second avoid resampling.

Starting with version 11 of pulseaudio, it can reopen sinks with their native samplerate. Furthermore you need to take care, that your sink has a wide enough output format.

To properly resample samperates that are not available with your sound card, e. As alternate sample-rate we suggest The last setting will increase the resample quality from pulse and therefore the CPU load quite a lot.

Again: Resampling is only done, when the sink output does not match the data you throw onto it. But as most normal mp3s are in The overwriting of the resample-method is for this use case. Note: Doing so may cause problems!

When your audio is much too fast or crackles a lot or passthrough only produces noise, you might have a broken driver in use. Audio devices are disappearing with pulseaudio 8.

This is an issue with the module-switch-on-port-available module and will be fixed with pulseaudio 9. When Pulseaudio is configured to be multi-channel output, e. This is default pulseaudio server behaviour. Beware: This will also forbid PA to remix e. Starting with the upcoming kodi v17 Krypton the above behaviour is taken care within kodi. You don't have to disable remixing in pulseaudio anymore. That means content is output without further remixing by pulseaudio server if a sane mapping is possible.

Whenever we cannot map all input channels to the output we ask pulseaudio to do the mixing for us. Issue: Changing kodi's volume will change overall system volume, especially on song change this is an irritating behaviour.

The effect you hear is not done by kodi, but by a systemwide pulseaudio mis configuration. In fact it will cause the hardware volume or master volume to go up and down for every pulseaudio stream that changes its own volume. After a PA server restart, the volume handling is more intuitive. If you are at it, please inform your distribution about those issues, so that they can ship a more user-friendly default with next release. At the time of writing, affected distributions: Debian.

From Official Kodi Wiki. Jump to: navigationsearch. If you have another application hogging the device, e. Chrome or Skype, passthrough won't work. Even applications that simply monitor the device, such as SoundWireServer, will prevent passthrough from working.I have been unsuccessfully trying to get pulseaudio working as sound server within a LXC. So I want to grant access the LXCguest to the sound card hw and let pulse take over. I will afterwards expose the socket for other containers.

Notice that I am able to run pulseaudio in the host and share the socket with the pulseaudio within LXCguest.

I will try to enumerate all relevant information that I have tested so far, but I did a lot of trial an error and i may miss something. Notice that i added them to a hand made pulse group and to the discouraged audio group. Without the last one, not even alsa will work on the guest. The shared card is the MoBo soundcard. I needed the user to be in the audio group to do this in the host:. In the host.

Notice that I never installed the fluidsynth as stated in the wiki. I have to specify the cgroup and mknod of the different char files belonging to the pci. This is part of my config and autodev of the LXC the config of the lxc. I think there is something wrong with my pulseaudio in the guest. Independently of the LXC or not. I face too many times of obvious packages not installed in the LXC archlinux template that drove me crazy in the past.

I kept researching and took a look at journalctl dohand it seems that somehow alsa. I dont know why pulse is not able to auto-detect the shared audio card. If you invoke the card directly it will work O. You could try enable-memfd. I've not tinkered with LXC so this is just a thought, one that may be useless to you. Good luck.

Dog football puns

I will check how to enable the memfd, but right now is far more easier to load the card manually than researching this new feature. Just to clarify are you using the legacy lxc or the new lxd with the new lxc 2. The flockport example was my starting point also, i have been forced to come back to it. Notice that I managed to effectively run the pulse daemon into a LXC, you just need to load the cards manually as pulse modules, since udev module doesnt work within a container.Review your favorite Linux distribution.

I found a file to fiddle with online, but it doesn't exist at that location here. I need to get pulseaudio talking to hdmi. I did it on this box on I just need hdmi sound in Pulse. A reboot doesn't sort it, and pulse doesn't see hdmi. Any ideas of grappling with pulse? Yes, it's basically useless. In alsamixer, I fiddled with the menus, and got up loads of columns.

I decided hdmi was the PCM, adjusted that. I'm pessimistic, but I'll go looking for my old config stuff. Originally Posted by Richard Cranium. No different on the huge kernel; no hdmi in pavucontrol. From experience, I know this is bitchy in this laptop.

Why I don't really know Right, even on my own kernel, I get the following: Code:. Why I don't really know. The only thing I did different to get it working was to extract a 'microphone' whose existence pulse wouldn't acknowledge and still doesn't out of it's socket. I believe the same madness applied to earphones.

No form of reasoning deductive or otherwise brings me to that as a cause. But I changed no files. Maybe a full restart instead of a reboot? They're different inside a pc. I learned that in the early days.I always use pavucontrol to change the output to hdmi, and the mixer shows sound playing, but nothing comes from the TV.

I have seen those workarounds, but I am using pulse audio and they are using alsa, so my default asound. When you just run alsa, like those guys, your asound. So, I'm not sure if those changes will do anything but break it worse. I guess it can't hurt to try it anyway The nvidia section of the pulseaudio page on the wiki looks similar. I don't see anything in the instructions there that would make the solution nvidia-specific. Maybe, the name of the section needs changing to something more generic than just nvidia.

Eg, it may be more appropriate to call it just "HDMI Configuration" with a note about which cards it's known to apply to. Hi guys, I'm having the exact same problem, but I can not get it to work with the workaround in the wiki.

I've confirmed I can play sound with aplay -D plughw:1,7. This thread is over 3 years old.

Pulseaudio does not generate combined profiles by default, you can choose either digital or analog profiles. The easiest way to make both outputs available is to add a combined profile to the end of default profile configuration file:. Although this works, pulseaudio has a nasty habit of falling back to auto-generated profiles, so you may eventually need to set your card back to the combined profile.

The best way to overcome this is by writing a custom config with disabled auto-profiles. Copy default. Now that you have your custom profile you need to tell pulseaudio to use it. This can be done by defining an udev rule :.

Now tell udev to reload sound subsystem udevadm trigger -ssound and restart pulseaudio. Your sound card should now use only the defined profile and have both analog and digital outputs available. PulseAudio allows for simultaneous output to multiple sources. In this example, some applications are configured to use HDMI while others are configured to use analog.

Multiple applications are able to receive audio at the same time. Restart PulseAudio, run pavucontrol and select the "Output Devices" tab. Three settings should be displayed:.

A drop-down list should be available for the running program to select one of the three sources. The original title for this section indicated the problem is specific to nVidia cards. As seen in this forum thread other cards are affected as well. The rest of the section will use an nVidia card as a case-study but the solution should carry over for people using other affected cards.

If there is no audio, then try substituting a different device on my card I had to use card 1 device 7.

Then, open the output tab. There should now be two HDMI outputs for the graphics card. Test which one works by selecting one of them, and then using a program to play audio. For example, use VLC to play a movie, and if it does not work, then select the other.
