On Ubuntu I use a backported kernel and 'options snd-hda-intel model=dell-m42' in /etc/modprobe.d/alsa-base There was someone who asked for me to keep him or her updated with this effort and this is why I'm posting back to the post with this info. Well, a few months later and sound jack sound isolation issue is corrected. Upgrade to ALSA-DRIVER 1.0.16 and you should be fine. You might have to unmask it. Sound now ceases to emanate from my speakers when headphones are plugged into my laptop (HP dv6645us).

I checked the ALSA-Project page and it seems since 1.0.14rcX they have pretty much halted development on the Connexant CX20549 Codec which uses Realtek 282... There is a patch from linuxant.com but it's takes a lot more steps to configure. I'm pretty sure I'll solve the issue by editing my own configuration using theirs as a reference point. I'm probably going to have to downgrade my version of alsa-driver or use the svn sources. -- gentoo-user@lists.gentoo.org mailing list

Any pointers to documentation will be appreciated. I had an issue very similiar to this when I purchased my Acer Extensa 5620. After looking around for a long time I found out that the version of alsa that was being used in my kernel at the time didn't well support my sound card. I'm not sure about what alsa version is being used in the latest kernel now but it doesn't hurt to give it a go. Also, I had to modprobe snd_hda_intel with model=acer. Before inserting the module with the model param I was at the same exact spot you are at now. hope this helps -- Dan Dexter signature.asc Description: This is a digitally signed message part.
