We are designing a new USB sound card that combines analogue and digital outputs using the USB 2.0 audio driver. The incoming audio stream can be 32bit 44.1 to 192 To combine the analogue and the digital I am using a multi, but cannot specify different formats for the slaves when using a multi. Ideally I want to set the analogue at 32bit and force the digital to 24bit This all seems to be working ok without the format being specified, however I would like to know if anyone knows a way to fix the format for each output when using a multi? Any suggestions would be greatly appreciated. #/etc/asound.conf pcm.player1 { type softvol slave.pcm "player1v" control.name "p1.m" control.card 0 resolution 2 } pcm.player1v { type softvol slave { pcm "player1mix" } control { name "p1.v" card 0 } } pcm.player1mix { type plug slave.pcm { type multi slaves { a { pcm "analog1r" channels 2 } b { pcm "digital1r" channels 2 } } bindings [ { slave a channel 0 } { slave a channel 1 } { slave b channel 0 } { slave b channel 1 } ] } ttable [ [ 1 0 1 0 ] [ 0 1 0 1 ] ] } pcm.analog1r { type rate slave analog1s } pcm_slave.analog1s { pcm "hw:0,0" rate 48000 } pcm.digital1r { type rate slave digital1s } pcm_slave.digital1s { pcm "hw:0,1" rate 192000 } Ed Stark |
