Hi Mitch, Yes the bug you mentioned is similar, however does not appear to be the same. I've done a lot of testing to find the best solution for me.
Part of the problem finding a solution was that this model of computer electronically switches the audio output between either the Internal Speaker or the Headphone/Lineout. This is not a mechanical switch, hence incorrect drivers seem to prevent the electronic switching of the internal speaker off even though I have something plugged into the Lineout/Headphone. I did try the backports but they did not work and removed them for this testing. I found that the following lines in /etc/pulse/default.pa caused distorted audio. I tried these lines once after trying the model=hp line. So I restored them to their defaults. load-module module-udev-detect ignore_dB=1 load-module module-alsa-sink control=PCM "options snd-hda-intel model=acer" didn't work. But I decided to check what other models I could use in the ALC260 range. I dumped a bunch of model lines in and commented them in and out one at a time and wrote notes as I went. Here is what I found: # HP # Works, albiet Internal speaker control must be at 0% volume but NOT muted for Headphone/Lineout to work. # Volume control then no longer works as it tries to amp internal speaker control to 50% when increasing the volume. #options snd-hda-intel model=hp # HP 3013 variant # Works well and will switch audio output correctly. However volume mapping # has sudden drop off around 20%, anything above makes hardly any difference. #options snd-hda-intel model=hp-3013 # HP DC7600 # Despite this being the exact model of my PC this does NOT work... at all. (However the dc7600 comes # in two versions, desktop and slimline, and since I have the slimline I presume this only works for the desktop) #options snd-hda-intel model=hp-dc7600 # Fujitsu S7020 # Doesn't work. #options snd-hda-intel model=fujitsu # Acer TravelMate # Internal speaker works. No controls and no sound from headphone and lineout. #options snd-hda-intel model=acer # Will laptops (PB V7900) # Works really well! Volume is no longer mapped to "speaker" and the internal speaker and # lineout/headphone now switch properly. options snd-hda-intel model=will # Replacer 672V # Sends a high spike through the sound card which will cause the speakers to click even if the volume is muted on the # external amp. Seems to work otherwise but not fully tested. #options snd-hda-intel model=replacer -- No sound after upgrading from 8.10 to 9.10 https://bugs.launchpad.net/bugs/515422 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
