There are so few changes in Intel/Realtek HDA ALSA code between 3.0 and 3.0.11 I thought you could identify the culprit just by looking at the list. ALSA: fm801: Fix double free in case of error in tuner detection ALSA: fm801: Gracefully handle failure of tuner auto-detect ALSA: HDA: Add new revision for ALC662 ALSA: hda - Add position_fix quirk for Dell Inspiron 1010 ALSA: hda - Add support for 92HD65 / 92HD66 family of codecs ALSA: HDA: Add support for IDT 92HD93 ALSA: HDA: Cirrus - fix "Surround Speaker" volume control name ALSA: HDA: conexant support for Lenovo T520/W520 ALSA: hda - Disable power-widget control for IDT 92HD83/93 as default ALSA: hda - Don't add elements of other codecs to vmaster slave ALSA: hda - Fix ADC input-amp handling for Cx20549 codec ALSA: HDA: No power nids on 92HD93 ALSA: hda/realtek - Avoid bogus HP-pin assignment ALSA: hda/realtek - Fix auto-mute with HP+LO configuration ALSA: hda/realtek - Skip invalid digital out pins ALSA: hda - Remove bad code for IDT 92HD83 family patch ALSA: pcm - fix race condition in wait_for_avail() ALSA: ua101: fix crash when unplugging ALSA: usb-audio: Check for possible chip NULL pointer before clearing probing flag ALSA: usb-audio - Check the dB-range validity in the later read, too ALSA: usb-audio - clear chip->probing on error exit ALSA: usb-audio - Fix the missing volume quirks at delayed init If you have no ideas about which patch could have broken things, I will try to figure it out by bisecting.
