[Pkg-alsa-devel] Bug#768383: After installing new kernel, no sound at all

[Alan McConnell]

I reported early the hideous crackling sound that was emitted
whenever I ran anything requiring sound on my new wheezy
install.  I was then running   vmlinuz-3.2.0-4-686-pae .  I
was advised to install a new kernel.  vmlinuz-3.16-0.bpo.2-686-pae
was available as a backport, so I installed it.   Now I have
no sound whatsoever, and, seemingly, no way of setting sound to
play.  

Here is some information about my system, gleaned mostly from
/proc/asound/.

cat /proc/asound/version  yields:
Advanced Linux Sound Architecture Driver Version k3.16-0.bpo.2-686-pae
	 This seems to imply that ALSA is compiled into this kernel

cat /proc/asound/cards yields:
 0 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xf7d14000 irq 46
 1 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf7d10000 irq 44
	   I already knew that I had two sound cards.  I have read
	   that alsa supports up to 8!

cat /proc/asound/devices yields:
  1:        : sequencer
  2: [ 1]   : control
  3: [ 1- 0]: digital audio playback
  4: [ 1- 0]: digital audio capture
  5: [ 1- 2]: digital audio capture
  6: [ 1- 0]: hardware dependent
  7: [ 0]   : control
  8: [ 0- 3]: digital audio playback
  9: [ 0- 7]: digital audio playback
 10: [ 0- 8]: digital audio playback
 11: [ 0- 0]: hardware dependent
 33:        : timer

cat /proc/asound/hwdep yields:
01-00: HDA Codec 0
00-00: HDA Codec 0

cat /proc/asound/modules yields:
 0 snd_hda_intel
 1 snd_hda_intel


 I believe I have a good kernel, my speakers are old, plugged in
correctly, and turned on.  So -- I hope -- it is now a question
of configuration.  I hope that someone knowledgeable about ALSA
will tell me what to do further.

TIA,

Alan
