Hi,

The issue is reproducible on systems with an Intel Audio chip and a NVIDIA GPU
with HDMI output (detected as a soundcard).

When both conditions are met, PulseAudio does not detect the Intel Audio
soundcard anymore and no sound at all is output. The only workaround consists
in inserting garbage in /etc/pulse/daemon.conf to prevent it from loading (say,
a syntax error in the file). Then sound is back again.

I have NVidia blob 390.87, and I'm working with KDE.

Could you please fix the issue ?

Thanks a lot

Hi again,

I tested with pavucontrol and the Intel HDA audio controller simply
does not appear.

Looks like I'm not the only one affected, see :
https://unix.stackexchange.com/questions/452079/no-sound-unless-root-in-debian-buster

@Debian NVIDIA Maintainers -> the issue might also come from the
NVidia driver (misconfiguration), although it did not occur in Stretch
w/ BPO 390.87-4 driver.

Workaround :

In /etc/pulse/default.pa uncomment the following line :
load-module module-alsa-sink

Then everything goes back fine.

Looks like there's something wrong with PA detection module.

Hi,

Could reproduce this bug on an host without an NVidia GPU.

Workaround is still the same.

Could you please attach a verbose log of pulseaudio when the problem
occurs? Sounds like the udev module is not doing its job.

Hi

How do I get the verbose log ?

Use:

systemctl --user --runtime --full edit pulseaudio

Append a '-vvvv' to the ExecStart line

systemctl --user restart pulseaudio

And then get the log

journalctl --user-unit pulseaudio --since=sometimebeforerestarting > pulse
log

(You might need root to get the logs)

Verify that the log is not empty, and then attach it.

The log says:

module-udev-detect.c: /devices/pci0000:00/0000:00:1b.0/sound/card0 is busy:
yes

Some other program appears to be holding the device busy. Common culprits
include espeakup and timidity. You can further inspect with:

sudo lsof /dev/snd/*

Dear Maintainer,

I think I'm seeing this problem. Loading module-alsa-sink makes the device
appear though there's no inputs.

Workarounds for bugs #901148 and #901689 don't work.

My Nvidia driver version:

ii  nvidia-legacy-390xx-driver                  390.116-1    amd64
NVIDIA metapackage (390xx legacy version)

Best regards.

Sorry, the contents of the file /etc/pulse/default.pa in my last reply are
incorrect.

Lines:

load-module module-alsa-sink
load-module module-alsa-source device=hw:1,0

should be commented like this:

#load-module module-alsa-sink
#load-module module-alsa-source device=hw:1,0

Since that's how they were when the log was recorded.

Thank you so much for this.

I had the same symptoms after upgrading to Buster. Removing timidity
"solved" the issue.

As a default behaviour, this is pretty bad.

Is this a known issue? Should this be filed as another bug somewhere?
