 Posted: Sat Feb 17, 2018 10:56 pm Post subject: Audio device randomly not available |
 |
|
Dear Community,
Randomly (~every fourth boot of my notebook) my audio device is not available (only dummy output shown in Gnome). A reboot fixes it and I can play audio again.
Any idea how I can fix it?
| Code: | lspci -k
00:1f.3 Audio device: Intel Corporation Sunrise Point-LP HD Audio (rev 21)
Subsystem: Lenovo Sunrise Point-LP HD Audio
Kernel driver in use: snd_hda_intel
|
Many thanks.

When it is not available, is it still recognized by the kernel? Visible in alsamixer?
Seeing that you use Gnome, my guess is that it is probably pulseaudio messing up...

Very philosophic!
I am now booted with "dummy output" as the only audio device. As a normal user alsamixer only shows one master and as a device pulseaudio, nothing else. As root alsamixer shows my HDA Intel PCH. Speaker is 100/100, PCM 100/100
| Code: |
lenovo-yoga ~ # dmesg | grep audio
[ 1.632507] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC298: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:speaker

How do I check if pulseaudio messed it up?

I have realised that simply killing (pulseaudio -k) and starting (pulseaudio --start) pulseaudio fixes the issue, if the device is not available since boot.
Nothing blocks pulseaudio (recommendation from the Wiki to check):
| Code: |
lenovo-yoga ~ # fuser -v /dev/snd/*
BEN. PID ZUGR. BEFEHL
/dev/snd/controlC0: gdm 2553 F.... pulseaudio
|
After restarting pulseaudio, fuser also reports controlc0 as a user:
| Code: |
username@lenovo-yoga ~ $ fuser -v /dev/snd/*
BEN. PID ZUGR. BEFEHL
/dev/snd/controlC0: username 22261 F.... pulseaudio
|
Any idea how to fix this?

I have compiled pulseaudio with those flags:
11.1{tbz2}(03:43:26 27.02.2018)(X alsa alsa-plugin asyncns bluetooth caps dbus gdbm glib gnome gtk ipv6 orc ssl tcpd udev webrtc-aec -doc -equalizer -jack -libressl -libsamplerate -lirc -native-headset -neon -ofono-headset -oss -qt4 -realtime -selinux -sox -system-wide -systemd -test -zeroconf ABI_MIPS="-n32 -n64 -o32" ABI_PPC="-32 -64" ABI_S390="-32 -64" ABI_X86="32 64 -x32")
If there is more information what I can provide you for your appreciated support, please let me know.
