conexant high definition audio driver for ubuntu

Inside this post you’ll find further instructions, which are adapted from a text document Tobin sent his tester group via e-mail. That said, it’s a huge improvement over out of the box sound support for Ubuntu (which is ALSA 1.0.11).

I find that it’s not so bad, as long as I keep a launcher to gnome-volume-control set up so that I can control it, knowing these rules. Tobin has told me that the chipset produced by Conexant is particularly weird, which is why he had to this.

The master volume control effectively modulates both of these. The second one controls the volume only between the sound system and the speakers (and thus, will have no effect on the sound when the headphones are plugged in). The first one controls the volume directly from the sound system. I’m noticing some sound quality issues at high volumes, and in order to get it to work Tobin had to essentially enable two PCM channels (PCM and PCM-2), which have a very strange behavior. The built-in mic on the monitor now works, though obviously with worse sound quality due to ambient noise.The microphone port now works, with great sound quality.The headphone port now works, and the speakers automute when the headphones are plugged in.

His patches over ALSA 1.0.14rc3 enable the following new features: I’ve been in contact with an ALSA hacker, Tobin Davis, over a series of patches that provide support for the sound chipset (intel-hda) that is part of the HP DV2000 laptop. If I get a few moments, I will revise these instructions in the future. Note: This entry is now wildly out of date.
