Pulseaudio = no sound via hdmi, pulseaudio --kill = everything fine

Utini · 2015-10-15 08:25:31

Hey there, I am on a Dell XPS 15 9530 running Arch with alsa + pulseaudio and suddenly don't get any sound over HDMI anymore.

If I "pulseaudio --kill" then the sound via HDMI works just fine. I recently also had troubles with no sound via speakers, pulseaudio --kill fixed that (see the @edit's at the end of the post).
Also for Audacious:
If it uses ALSA Output with -> Pulseaudio default server -> No Audio
If it uses ALSA Output with -> Speakers -> Normal Audio

How ever, it seems like pulseaudio automatically restarts after killing? And then pulseaudio is running, but the sound suddenly works as well.

Also: Some app "lock" on one output device. E.g. I just started telegram and pavucontrol has it listed with HDMI as output device altough HDMI isn't even connected. I can't switch its output to analaog stereo, it just stays at HDMI.

aplay -l (when HDMI is plugged in):

**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

card 1: PCH [HDA Intel PCH], device 0: ALC3661 Analog [ALC3661 Analog]
  Subdevices: 0/1
  Subdevice #0: subdevice #0

I am not sure why there are 3 HDMI's listed when I only got one (+ displayport + spid/f).

aplay -D plughw:0,3 /usr/share/sounds/alsa/Front_Center.wav

aplay: main:722: audio open error: Device or resource busy

No sound...

Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono

No sound...

Pavucontrols lists HDMI / Displayport as output device + pluggend in.
The volume for PCM is on max in the audio mixer and not muted.

In e.g. VLC I select "Audio -> Audio Device -> HDMI" and the sound disappears.

Sound via HDMI has worked before and I havent changed much except changing my /etc/pulse/default.pa (notice the #load-module module-switch-on-connect which I had enabled but now disabled again):

Any ideas?

@edit: And now suddenly without doing ANYTHING sound related I get no more sound via my laptops speakers. On the other hand pavucontrols now shows sound being played via HDMI, altough no HDMI is connected.
@edit2: "pulseaudio --kill" fixed my speakers.
@edit3: with pulseaudio still killed, sound via HDMI works as it should.. so pulseaudio is causing the troubles?

Another thing I noticed: When I run VLC with "optirun" then I get sound via hdmi for like half a second. Then it is mute again. If I switch the audio device to "stereo analog" then my laptops speakers will output the sound. If I switch back to HDMI then I get "half a second of sound" again :S

Any ideas ?

Give the output of

sudo fuser -v /dev/snd/*

aplay error message leads me to believe that something blocks pulseaudio from accessing the device. Thrown in

pacmd list-cards
pacmd list-sinks

for good measure

It seems like sound via HDMI is there for 0,5seconds sometimes. I also noticed this on VLC without "optirun". Just right after switching to the HDMI-Output I get sound for 0,5seconds (sometimes). I have no clue why.

Output (without TV connected with HDMI):

Can you kill panel-17-mixer and check if you are still having issues? (Might have to kill pulseaudio as well and let it respawn so it can properly take over the card) Do you have pulseaudio-alsa installed? any /etc/asound.conf or .asoundrc in your $HOME directory we should know about?

Yes, pulseaudio-alsa is also installed.
No .asound file in my $HOME directory.

/etc/asound.conf:

# Use PulseAudio by default
pcm.!default {
  type pulse
  fallback "sysdefault"
  hint {
    show on
    description "Default ALSA Output (currently PulseAudio Sound Server)"
  }
}

ctl.!default {
  type pulse
  fallback "sysdefault"
}

# vim:set ft=alsaconf:

Well.. for example right now "panel-17-mixer" is not running (no idea why not). And I still get this bug... for 1 second there is sound via HDMI, then it is silent.

sneida@_____:~$ sudo fuser -v /dev/snd/*

@Edit:
I am not able to increase the duration of the sound output via HDMI if I let a video play for a few minutes via laptop speakers. When I then switch to HDMI output, the audio will be for 2-3 seconds instead of just 1 second. The audio quality via HDMI is terrible though.

Also I did "Pulseaudio --kill" while HDMI was connected to let pulseaudio to a "re-scan":

sudo fuser -v /dev/snd/*

Edit2:
I continued playing around, re-installed pulseaudio-alsa... Checked that pavucontrol lists the HDMi port as plugged in...suddenly I was able to play sound via HDMI for nearly 10 seconds...in terrible quality though. And then it was silent again. -.-

Maybe this helps?

Could it be a buffering problem?
Or is something disabling the sound as some kind of "power saving feature" ? E.g. TLP ?

Edit #6578576:
I can now output sound via HDMI (since re-installing pulseaudio-alsa) but it is in terrible quality. Also: As soon as I move the mouse (e.g. via touchpad) the sound is gone

Basically: I switch from laptop speaker output to HDMI output and have terrible sound via HDMI. Once I move the cursor -> silence !

I also tried this with AC connected and without, both give me the same problem.

Edit: Same thing happens with audacious (as with VLC). So not VLC related.

Oh bloody hell.. I found the problem.. it is "intel_immou"...

Changin the kernel line option from "intel_immou=on" to "intel_iommu=igfx_off" fixed the issue... but does this now also mean that intel iommou isn't activated anymore ?

Pulseaudio = no sound via hdmi, pulseaudio --kill = everything fine
