Hi, no chance so far, just to be sure I got you right: 1. /dev/dsp0.9 created when basename_clone = 1 2. virtual oss started with -T /dev/sndstat -C 2 -c 2 -r 48000 -b 24 -s 8.0ms -R /dev/null *-P /dev/dsp0 -d dsp0.9* -M x,0,0,0,0,0 -M x,1,1,0,0,0 -t dsp.ctl -i 10 -S Still nothing when capturing. Environment: trying to grab audio from Firefox under KDE. Firefox is compiled with PULSEAUDIO on. When I enable virtual_oss and then start KDE there are no devices and the mixer does not work, so I cannot set the default playback device nor assign another playback device to Firefox when it outputs audio. It relays on hw.snd.default_unit (which happens to be set to 0). Furthermore when virtual_oss is started other apps behave inconsistently: vlc only shows the virtual_oss device in the list of output devices, all the other are gone, but audacity correctly shows the other rec devices as well as virtual_oss. What am I doing wrong? Thank you.
