Karsten, Firstly, as you have a WinTV 401, have you looked into using the btaudio driver from video4linux instead of the ALSA one? Info here says the 401 card should work without problems: http://linuxtv.org/v4lwiki/index.php/Btaudio Setting up btaudio is also detailed here: http://www.mythtv.info/moin.cgi/BtaudioHowTo Secondly, if /dev/dsp or /dev/dsp0 does not work (is it a device not found error?) this likely shows that the OSS emulation for ALSA is either not installed or not configured properly. (The ALSA-OSS lines are missing from your modprobe.conf for example) The ALSA site has the following page of info for the bt878: http://www.alsa-project.org/alsa-doc/doc-php/template.php?company=Brooktree&card=.&chip=Bt878%2C+Bt878a&module=bt87x Nick _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
