[320-1020m, IDT 92HD91BXX, Speaker, Front] Playback problem

[John Schofield]

This is an HP TouchSmart 320, model number 320-1200m.

Sound to headphone jack works properly, but sound to built-in speakers does not work. I have installed Windows, and with Windows 7 installed, all audio hardware works properly, so this isn't a hardware fault.

I've looked at https://help.ubuntu.com/community/HdaIntelSoundHowto and have been unable to find my card in http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt .

I have tried adding almost every conceivable model in the line "options snd-hda-intel model=MODEL" line I added to /etc/modprobe.d/alsa-base.conf.

I've gone to Control Center -> Sound Preferences to attempt settings that make sound work. The "Hardware" tab shows one device: "Internal Audio 1 Output / 1 Input Analog Stereo Duplex." There are two output profiles listed in the selection box at the bottom of the tag: Analog Stereo Duplex and Analog Stereo Output. Neither cause sound to emit from the speakers.

I've also run alsamixer on the command-line and ensured that everything is set to maximum and nothing is muted.

I have the same symptoms in 11.04 and 11.10.

Status changed to 'Confirmed' because the bug affects multiple users.

Was redirected here by (markrijckenberg) for my bug, so I figured I'd drop in my ALSA script output in here too.

Not to bump unduly, but has there been a fix I've missed or any word on progress to this bug?

I have a similar problem on the same hardware: IDT 92HD91BXX on a dell 14z inspiron 5423 ultrabook. Instead of no sound, white noise is continuously emitted from the sound card (only from speakers, never when using headphones). Other people seem to be affected, as documented in this Ubuntu forum thread:

http://ubuntuforums.org/showthread.php?p=12356165

After some experimenting I found a workaround and posted it as an answer to a question on askubuntu.com: http://askubuntu.com/questions/192185/12-04-dell-14z-inspiron-5423-ultrabook-sound-noise/217672 . I hope it can help debugging the issue.

I attach the python script I use for getting rid of the white noise at boot.

the virtual master playback volume 's dBmin should be as same as its slaves

you have to send email to alsa devel mailing list

control.12 {
  iface MIXER
  name 'Master Playback Volume'
  value 64
  comment {
   access 'read write'
   type INTEGER
   count 1
   range '0 - 64'
   dbmin -9999999
   dbmax 0
   dbvalue.0 0
  }
 }

send email to the author of these patches

this patch changes the code to create vmaster always even on STAC9200 and STAC925x. The former "Master" on these chips are renamed as "PCM" now.

http://git.kernel.org/?p=linux/kernel/git/tiwai/sound.git;a=commit;h=2faa3bf15ba69fa12bc53926b88982b3875abb3f

change the TLV dB information for the Master volume
  on all Sigmatel HDA codecs to indicate the the minimal volume setting
  actually mutes.
