ALSA: HDMI Audio stops working after PulseAudio started/stopped
Hi,
I have been diagnosing an issue with HDMI Audio Out for a few weeks and I am stuck.
I would appreciate some help and/or pointers to other boards for more ALSA/PulseAudio questions (I am not even sure right now whether the issue is caused by ALSA or PA).
In short:
After booting, before PulseAudio has started, sound works when going through ALSA directly (through aplay -D plughw:0,3).
When starting PulseAudio (in the course of an X11 session, but the same happens when running PA in system-wide mode), HDMI output is visible in PA but no sound can be heard when playing.
When stopping PulseAudio again, and going through ALSA directly again (aplay as above), no sound is heard.
At this point, only a reboot helps.
I suspect that PA is re-configuring something within ALSA but my knowledge of ALSA is too limited to go on from here.
Eventually, I would like to get PA to work, of course, but it seems like PA is changing/breaking something in ALSA so I feel like I am tackling the root course by finding out why ALSA stops working.
In the last weeks, I tried several things to no avail. I am trying my best to reconstruct what I tried, please let me know if I can provide more info:
Hardware: Intel NUC NUC11PAHi5
HDA Intel PCH (this seems to be my sound card?)
ALC256 (this is the "codec"? not sure what that means though... the semantics of "codec" in ALSA do not seem to match my understanding of that word)
The HDMI port in question is connected to a Philips Smart TV (for testing, I am using both the built-in sound of the TV as well as a connected sound bar, both either work or don't work at the same time, so it's not the sound bar that's the issue)
When using plughw:0,3 as a device with aplay, I hear sound (as long as I haven't started PA yet), so that is the device I need (for some reason I have 11 HDMI ports visible by ALSA, so I had to track that down)
The commands I use to test audio through alsa are the following, and they all either work or not work at the same time:
speaker-test -D hw:0,3 -c 2
aplay -D plughw:0,3 /root/Noise.wav (that wave file is coming from /usr/share/sounds/alsa)
My alsa-info before starting PulseAudio, when audio works: http://alsa-project.org/db/?f=f264e3040 … 9bb4a9f49f
My alsa-info after starting PulseAudio, when audio stops working: http://alsa-project.org/db/?f=588cbee7e … 4380619f8f
The files seem to have no significant difference (except for timestamps and an audio log about the PA unit being started in between).
Any help would be appreciated. I am very happy to provide more info, test kernel options, module options, try a custom compiled kernel etc.
Thank you in advance!

Re: ALSA: HDMI Audio stops working after PulseAudio started/stopped
Post
sudo fuser -v /dev/snd/*
pactl list cards
pactl list sinks
pactl list sink-inputswhile trying to play from PA. in code tags
That these speaker-test invocations start to fail while the card is in active use by PA is normal and expected you'd usually route all playback via PA.
