Sound has been missing on my wheezy for some time until your mail prompted me
to investigate it.
Running aplay test.wav produces no sound.
The output of aplay -l is:
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI_1 [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: HDMI_1 [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: HDMI_1 [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 0: 92HD91BXX Analog [92HD91BXX Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
Running aplay -D hw:1,0 test.wav reports an error and produces no sound:
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 11025 Hz, Mono
aplay: set_params:1087: Channels count non available
But sound started to work fine after I edited $HOME/.asoundrc like this:
pcm.!default {
type plug
slave {
pcm "hw:1,0"
}
}
ctl.!default {
type hw
card 1
}
The symptoms are not the same as yours. aplay doesn't play sound when I select
the PCM device on the command line. But, with audacity, if I explicitly select
ALSA as output and device hw:1,0, sound comes out. So, I may have another
problem that prevents aplay from running when the PCM device is specified and
the above solution may still help you.
BTW, I have pulseaudio installed in case it matters.
