[IDT 92HD73C1X5] No sound from headphone jacks

[Avdi Grimm]

Runing Lucid beta 2 on a brand new Dell Studio XPS 16. This laptop has two headphone jacks. Plugging headphones into either jack mutes main speaker audio, but audio does not play back through the headphones.

The headphone jacks are confirmed to work under Windows 7, but I have not tried it under any other version of Linux.

Changing the "Connector" option in Sound Preferences to either "Analog Headphones" or "Analog Line Out" has no effect.

I've also tried installing xfce4-mixer and switching various channels on and off, with no luck.

Please use linux-alsa-driver-modules-$(uname -r) from ppa:ubuntu-audio-dev.

[Daniel Letzeisen (dtl131)]

You might also consider trying a keyword in alsa-base.conf:
gksu gedit /etc/modprobe.d/alsa-base.conf
Copy and paste this:
options snd-hda-intel model=KEYWORD
where KEYWORD is one of the following (e.g. dell-m6)
http://www.mjmwired.net/kernel/Documentation/sound/alsa/HD-Audio-Models.txt#378
Save. Quit. Reboot.

Thank you Daniel, the linux-alsa-driver-modules-2.6.32-21-generic package from ppa:ubuntu-audio-dev fixed the issue.

[Avdi Grimm (s-launchpad-inbox-avdi-org)]

This just broke again as of updating yesterday. I still have ppa:ubuntu-audio-dev in my sources.

[Avdi Grimm (s-launchpad-inbox-avdi-org)]

I made sure no alsa-modules other than the PPA ones were installed, and re-installed the PPA modules. Headphone audio works again.

[madbiologist (me-again)]

If you uninstall the PPA modules and install the kernel from Lucid-proposed, is the problem fixed?
