Is this what you are referring to? # a52 plugin configuration # $Id$ pcm.a52 { type a52 # Default : #card 1 # 0 #rate 44100 # 48000 #channels 4 # 6 #bitrate 256 # 448 #format S16_BE # S16 (Native-Endian) hint { description "A52 Output Plugin" } } I tried putting this file (a52.conf) in both /etc/alsa/pcm and /usr/share/alsa/pcm. I still only have "stereo iec958" selections in the Configuration tab. Thanks, jim
