For further inspection I need some extra information. Please create a screenshot. Please post the ouput of "amixer" (or "amixer -c 1" or any other number that corresponds to the affected soundcard). Please also post the permissions of your sound card devices, using getfacl /dev/snd/controlC0 (or controlC1 or any other number that corresponds to the affected soundcard). Here are the permissions on all dsp devices: $ getfacl /dev/dsp* # file: /dev/dsp0.0 # owner: root # group: wheel user::rw- group::rw- other::rw- # file: /dev/dsp0.1 # owner: root # group: wheel user::rw- group::rw- other::rw- # file: /dev/dsp0.2 # owner: root # group: wheel user::rw- group::rw- other::rw- # file: /dev/dsp0.3 # owner: root # group: wheel user::rw- group::rw- other::rw- # file: /dev/dsp0.4 # owner: root # group: wheel user::rw- group::rw- other::rw- # file: /dev/dsp0.5 # owner: root # group: wheel user::rw- group::rw- other::rw- Created attachment 43824 [details]

screenshot of kde4 mixer in FreeBSD after boot, Capture checkbox on pcm channel is off and is read-only, even though it was 'on' before the graceful kde4 shutdown.
Here is the mixer settings after system boots up: $ mixer Mixer vol is currently set to 46:46 Mixer pcm is currently set to 58:58 Mixer line is currently set to 75:75 Mixer mic is currently set to 67:67 Mixer cd is currently set to 86:86 Mixer ogain is currently set to 100:100 Mixer line1 is currently set to 75:75 Mixer line2 is currently set to 66:66 Mixer line3 is currently set to 100:100 Recording source: mic I can only bring 'pcm' into 'Recording source' with 'aumix', not with kde mixer. kde mixer should set up 'pcm' by itself without the need for me to use 'aumix'. The requested amixer output is very important. Could you please post it? Repeating: Please post the ouput of "amixer" (or "amixer -c 1" or any other number that corresponds to the affected soundcard). Sorry, I didn't mention this explicitly in my orevious ports. amixer is ALSA mixer, and there is no ALSA (yet) on FreeBSD. FreeBSD is OSS only at the moment. Please let me know what you would like me to run. Confirmed for current in FreBSD kdemultimedia-4.4.5. Looks like I can reproduce the issue. Looks like Mixer_OSS::setRecsrcHW() is never called. This is either quite bizarre or a very very very old bug. If it is the latter it might be fixed by writing capture switch together with the volume levels. Yes, this is a very long standing bug. Fixing this was a nightmare. I needed to clean up very old and very obsolete code, and rewrite a lot of things. After that record switches worked, but volume levels were broken (again, only for OSS). The latter failure was without good reason. I ended up rewriting Mixer_OSS::readVolumeFromHW() in the style of the ALSA driver. Magically that worked. To make long things short. It seems to work now again, and KMix backend interfaces have been cleaned up a bit (which is a really good thing). Thank you for fixing this long standing problem! FreeBSD uses OSS and PulseAudio, no ALSA due to the 'L' letter in it. But KDE on FreeBSD still only works through OSS and has this nasty bug that I have to work around once in a few days.
