Latest working kernel version: 2.6.28 Earliest failing kernel version: 2.6.29-rc7? Distribution: Ubuntu Jaunty Hardware Environment: Dell Vostro 1400 Software Environment: Alsa/Audacious Problem Description: Inserting a headphone does not kill sound on built-in speakers, there is no separate headphone volume/mute control in alsamixer under 2.6.29-rc7 Steps to reproduce: boot 2.6.29-rc7, play audio, plug headphone: still sound from internal speakers (AND sound from headphones). No headphones volume/mute in kmix or alsamixer.
Try the very latest Linus git tree. A couple of fixes for Dell laptops are in after rc7. If it still doesn't work, try sound git tree (master branch) git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git Anyway, please run alsa-info.sh with --no-upload option and attach the generated file. This will contain more detailed hardware information. The script is found at: http://www.alsa-project.org/alsa-info.sh
Created attachment 20515 [details] alsa-info (ran as user) This is the requested info. I'd prefer to stick with rc's when possible. They're on-the-edge enough for me as I'm running rc7 on a "production" laptop.
Then try rc8 released yesterday :)
It's fixed in rc8. Thx!
