[mythtv-users] State of ALSA after suspend / MythTV sound init magic

[Greg G.]

Hello,

I'm seeing a strange thing on my Mythbuntu box. When it wakes up from 
suspend (S3), ALSA (snd-hda-intel, NVidia GS8400) is not really fully 
there, for instance:

$ cat /proc/asound/card0/eld#1.0
monitor_present		0
eld_valid		0

speaker-test -r 48000 -c 2 -D hw:0,3 shows no erros but produces no 
sound. Now, when I watch any video/recording in MythTV, I _do_ get sound 
and:

$ cat /proc/asound/card0/eld#1.0
monitor_present		1
eld_valid		1
monitor_name		DENON-AVAMP

connection_type		HDMI
...

So is it that MythTV does to get back the sound right way without 
briefly starting the Myth Player? Is there any way to emulate the 
initialization with tools such as amixer etc? So far I tried w/o success:

- rmmod/modprobe snd-hda-intel
- alsa force-reload

TIA
