[ICH4 - Intel ICH6] Dell Latitude D610 - Master mixer doesn't affect headphone output

[Ben Gamari]

The Master mixer does not change the volume from the headphone output (which is affected by the headphone mixer). Instead it only seems to control the on-board speaker volume. This confuses PulseAudio greatly as the Master channel is merged into the volume mix.

Is there also a LED on this machine that indicates mute status?

No.

Can you append the following line to /etc/modprobe.d/alsa-base.conf and reboot?

options snd-intel8x0 ac97_quirk=hp_only

[Daniel T Chen (crimsun)]

@Ben Can you try the workaround that I posted in comment 4, please? I attached also a patch that fixes the symptom.

Sorry about the latency; I haven't had consistent access to the machine
over the last few days. I'll try it when I get back home tonight. Thanks!

Finally tested. Volume scales as expected with that quirk. Thanks!

Accepted linux into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Accepted into maverick-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Steve Conklin (sconklin)]

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

This patch was applied to Maverick as part of an upstream stable update, therefore it doesn't require individual verification.

[Clayton Kramer (clayton-kramer)]

I just reinstalled Maverick and applied all updates. Problem was only corrected when I performed comment #4.

[David Henningsson (diwic)]

@Ninjix, this is because this bug isn't released into maverick-updates yet, it's only present in maverick-proposed.
