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. http://git.kernel.org/?p=linux/kernel/git/tiwai/sound.git;a=commit;h=de8c85f7840e5e29629de95f5af24297fb325e0b -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/888703 Title: [320-1020m, IDT 92HD91BXX, Speaker, Front] Playback problem Status in “alsa-driver” package in Ubuntu: Confirmed Bug description: 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.
