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

Bug Description

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?

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

options snd-intel8x0 ac97_quirk=hp_only

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!

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.

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

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