[SOLVED] Audio issues on Dell XPS 9343 running current

dmcrtr · 04-08-2016, 04:59 PM

I'm running into an audio issue on my Dell XPS 9343 running slackware64-current.

When I boot my system and launch pavucontrol/alsamixer it launches normally, it continues to work using Firefox. However if I launch another media app (parole, vlc, etc) the audio no longer works and if I go back to pavucontrol/alsamixer I get

Code:

alsamixer
shm_open() failed: No such file or directory
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Protocol error

I tired to follow https://wiki.archlinux.org/index.php..._13_%282015%29 without much success.

If I add the conf file

Code:

/etc/modprobe.d/alsa-base.conf
options snd_hda_intel index=1,0

I get sound in vlc and parole again, but can't open the mixer, play videos in Firefox if I have another media app open.

this bug seems relevant https://bugzilla.redhat.com/show_bug.cgi?id=1255070

I'm pretty sure it was working fine until the 4.4 kernel update so I'm guessing its the I2S mode switch and the audio is defaulting to HDMI out.

Can you post the output of the following?

Code:

lspci -k | grep -iA 3 audio

But based on your aplay -l, I don't think it is defaulting to your hdmi as your card0 is listed as your analog device.

It's looking like this is related to firejail. I had been playing around with firejail the last bit and it seems like its interfering with the connection to pulse using the default profile. I'll post back when I have time to figure out a solution.

This solved the problem

https://firejail.wordpress.com/support/known-problems/

$ mkdir -p ~/.config/pulse
$ cd ~/.config/pulse
$ cp /etc/pulse/client.conf .
$ echo "enable-shm = no" >> client.conf
