Description of problem: Since I bought my computer and I installed Linux on it, I had this problem... Back in the day I never Found a REAL Solution and finally my solution (in Fedora) was installing "pavucontrol" to choose the Output Devices when I needed to Switch. Via the Pulse Audio Volume Control I was able to Mute speakers or Headphones at my will, even if I had both connected, this thing worked from F12 to F14 very well... (The same problem was present in every distro I tried and sometimes it was solved the same way -using pavucontrol- in other distros) But Now, I'm in F15 And my "magic workaround" doesn't work anymore... it doesn't matter wich device I choose as output, the PC simply don't mute one or another and my headphones and speakers sound at the same time, Can you tell me How to Fix this problem? P.S. I'm not sure, but I believe it's a problem with pulseaudio... Version-Release number of selected component (if applicable): N/A How reproducible: Play some music or sound in the PC with speakers and then plug the headphones Steps to Reproduce: 1.Play some music on the PC with the speakers plugged in and chosen as output 2.plug in the headphones Actual results: The sound comes out of Both speakers and headphones, the headphones don't mute the speakers when they're plugged in. Expected results: When the headphones are plugged in, they should mute speakers. Additional info: The Sound card is a HDA INTEL with the Realtek ALC662 rev1 Chip; As I said before, I'm using Fedora 15 KDE (64 Bit version) and I'm running ALSA v 1.0.23 with pulseaudio 0.9.22-5, The output of "lsmod | grep snd" is: snd_usb_audio 98871 1 snd_usbmidi_lib 18066 1 snd_usb_audio snd_rawmidi 20308 1 snd_usbmidi_lib snd_hda_codec_realtek 325262 1 snd_hda_intel 23694 3 snd_hda_codec 80822 2 snd_hda_codec_realtek,snd_hda_intel snd_hwdep 6368 2 snd_usb_audio,snd_hda_codec snd_seq 52438 0 snd_seq_device 6001 2 snd_rawmidi,snd_seq snd_pcm 78484 4 snd_usb_audio,snd_hda_intel,snd_hda_codec snd_timer 19593 2 snd_seq,snd_pcm snd 62686 18 snd_usb_audio,snd_usbmidi_lib,snd_rawmidi,snd_hda_codec_realtek,snd_hda_intel,snd_hda_codec,snd_hwdep,snd_seq,snd_seq_device,snd_pcm,snd_timer soundcore 6299 1 snd snd_page_alloc 7431 2 snd_hda_intel,snd_pcm Thanks! Hope this thing has a solution.
I'll close this bug, I solved it at the end (No one was able to help me sadly...) The solution was to find my chip on this list: http://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio-Models.txt and try one by one the different modules that where available for my chip, (Actually the "stack's correct one" didn't work, so I had to try them all;)To try & solve I had to create this file: "/etc/modprobe.d/snd_hda_intel.conf" and then I had to find this other file: "/etc/modprobe.d/dist-alsa.conf", then I started adding the classic "options snd-hda-intel model=xxxxx" in those two files, restarting for each change of model until my headphones/speakers problem got solved. at the end, Finally it worked with one model (Not the REAL MODEL/brand of the device or even PC, but it worked) and now when I plug headphones, the speakers mute, don't even need to use pavucontrol. Thanks!
