Hello,

Since kernel 3.0.11 I have quite terrible sound artifacts - random pops, clicks and short pauses (~500ms). Linux kernel 3.0.0 is *bug free*. So, some some of patches in kernel *3.0.11* broke the driver, the bug is, of course, present in kernels 3.1 and 3.2.

I'm attaching alsa-info.txt for your convenience.

Kernel's bugzilla is dead so I have no choice but to post about this problem on LKML.

Hello,
Since kernel 3.0.11 I have quite terrible sound artifacts - random pops, clicks and short pauses (~500ms). Linux kernel 3.0.0 is *bug free*. So, some some of patches in kernel *3.0.11* broke the driver, the bug is, of course, present in kernels 3.1 and 3.2.

Could you give alsa-info.sh output to check more details? Also, any chance to identify which 3.0.x release breaks the things?

thanks,

Takashi

alsa-info output was attached to my original mail posted into LKML, please check out you e-mail client.

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.

Ah, OK, I'll check it later. I'm still on vacation so I can't check in details.

Well, it's not too easy since the problem isn't deterministic. You can check the patches with ALSA: hda (or capital) and ALSA: pcm prefix.

That'll be helpful.
