[pulseaudio-discuss] My default sound devices are not retained after suspend or reboot

[Sebastien PIMENTA]

Hi,

Can you tell me where is the log file of the debug mode ?
I've
edited /etc/pulse/daemon.conf and uncommented log-level=debug but I can't
find the log file :S

Lennart : concerning the card indexes, I'm not sure
how to use the control device name, like you said.
One of my problem is
that I use darkice for recording and broadcasting and its conf file is set
up to record hw(1,0). If I don't edit /etc/modprobe.d/alsa-base.conf to fix
the sound card order, darkice will record the wrong audio card after a
reboot or suspend, because the card order changes.

Hmm, my educated guess is that some weird suspend script might
unload some
device/driver on suspend and reload it afterwards. In PA
this might cause a
different default device to be chosen. You might be able to find out more
by enabling debug logging in PA and
then checking syslog. (log-level=debug
in /etc/pulse/daemon.conf)

That is definitely a bad idea, but
probably not the cause of this
issue. Stable card indexes are a thing of
the past, as it breaks
hotplugging. There is also no need for it, as you
can use card names
(as listed in /proc/asound/cards in the []), or you can
use the
control device name, such as
hw:/dev/snd/by-path/pci-0000:00:1b.0.
Both of which are way more descriptive. Lennart
