I have a similar problem with my Acer TravelMate 4670, running Debian GNU/Linux Squeeze/testing. My card identifies itself like this to the system: $ uname -a Linux <hostname> 2.6.32-5-686 #1 SMP Wed Aug 25 14:28:12 UTC 2010 i686 GNU/Linux $ lspci | grep -i audio 00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02) Pulse version is as follows: $ pactl --version pactl 0.9.21-rebootstrapped-dirty Compiled with libpulse 0.9.21-rebootstrapped-dirty Linked with libpulse 0.9.21-rebootstrapped-dirty The card is set up with Alsa, and the modules loaded for sound is included in the attached file 'sound_modules.txt'. I have also attached /etc/asound.conf and /etc/asound.names (the latter is rather lentgthy. I suppose this is due to the fact that I have plugged in and removed several usb audio devices as time has passed...) The soundcard has the ability to route the mic directly to the output, i.e. when I run 'alsamixer -c0', the mic shows up both under the 'Playback' and 'Capture' categories. The 'Capture' category has the option of using two input sources at the same time, naming them 'Input Source' and 'Input Source 1'. I normally want 'Input source' to be the microphone, and 'Input Source 1' to be 'Line'. This is a rather fancy card for a laptop, is it not? ... The problem manifests itself in that using PA with KDE messes tings up. I tried with Gnome, and it seemed to work better. Note that Debian GNU/Linux Squeeze/testing uses KDE 4.4.5. The KDE WiKi page states that full support for PA in Phonon and KMix is available in KDE 4.5. Perhaps I wil have to wait for that to propagate to 'testing', but I might have to wait for a while; it is still not in 'sid'. What happens is this: After KDE loads the desktop, all the mixer levels seem to be reset to factory default levels, which are not appropriate. The worst part is that the mic in the 'Playback' category is unmuted and at a high level, and hence constantly feeds all the nearby sound to the speakers. If I turn the master volume up I easily get a feedback. I tried tapping the mic to see when in the KDE loading sequence the messup occurs, and it seems to be rather late, at least after the desktop appears, but before KDE has finished loading all the tidbits. I also tried with different backends for phonon; Xine and GStreamer both produce the same results. I even tried to replace start-pusleaudio-kde with start-pulseaudio-x11. Nothing changed. Disabling the '-restore' modules in default.pa did not help either. Please find attached the output from 'amixer -c0' before and after KDE loads. What is going on here? The only way I managed to get mixer levels properly set is by using 'alsamixer -c0' in an xterm, or running '/usr/sbin/alsactl restore 0'. I have previously stored the wanted settings by issuing '/usr/sbin/alsactl store 0'. Note that /usr/sbin is not in my path, and that alsactl is world executable. ;)Frode Frode Severin Hatlevik -- Da sa Gud: "Det bli lys!" Og det ble lys. ? ? ? ? ? ? ? ? ? ? ? 1.
