audigy2 platinum optical output question
in windows there is an option where you can set the passthrough method of the optical out to passthrough to a external decoder, basically so I can have my theater system decoded the ac3/dts signal whatever....
I have been doing a bit of research on the topic and I've come up with nothing regarding this exact issue but things that I'm not seeing in my emu10k1 config and such that I have seen others mention like maybe enabling a passthough method or enabling the live drive and remote. So basically is there a way to have the digital sound 5.1 signal bypassed by alsa and passthrough the optical to a external decoder, or possibly kaffeine isn't compatable with such an option? I also remember that PowerDVD had to be configured to passthrough also . all i have is this... # # Configuration for the EMU10K1 chip # <confdir:pcm/front.conf> EMU10K1.pcm.front.0 { @args [ CARD ] @args.CARD { type string } type hw card $CARD device 0 } <confdir:pcm/rear.conf> EMU10K1.pcm.rear.0 { @args [ CARD ] @args.CARD { type string } type hooks slave.pcm { type hw card $CARD device 0 } hooks.0 { type ctl_elems hook_args [ { name "Wave Surround Playback Volume" preserve true # don't lock a global control # lock true value [ 0 0 ] } { name "EMU10K1 PCM Send Volume" index { @func private_pcm_subdevice } lock true value [ 0 0 255 255 0 0 255 0 0 0 0 255 ] } ] } } <confdir:pcm/center_lfe.conf> EMU10K1.pcm.center_lfe.0 { @args [ CARD ] @args.CARD { type string } type hooks slave.pcm { type hw card $CARD device 0 } hooks.0 { type ctl_elems hook_args [ { name "Wave Center Playback Volume" preserve true # lock true value 0 } { name "Wave LFE Playback Volume" preserve true # lock true value 0 } { name "Headphone Center Playback Switch" index 1 preserve true # lock true value true } { name "Headphone LFE Playback Switch" index 1 preserve true # lock true value true } # if you have a creative's digital receiver, you can get surround/center/lfe # output through the digital jack. so, the following is commented out. # pay attention in case of analog output from the shared center/digital # jack! # { # name "SB Live Analog/Digital Output Jack" # preserve true # lock true # value 0 # } { name "EMU10K1 PCM Send Volume" index { @func private_pcm_subdevice } lock true value [ 255 255 0 0 255 0 0 0 0 255 0 0 ] } { name "EMU10K1 PCM Send Routing" index { @func private_pcm_subdevice } lock true value [ 6 7 0 0 6 7 0 0 6 7 0 0 ] } ] } } <confdir:pcm/surround40.conf> EMU10K1.pcm.surround40.0 { @args [ CARD ] @args.CARD { type string } type multi slaves [ { pcm { @func concat strings [ "cards.EMU10K1.pcm.front.0:CARD=" $CARD ] } channels 2 } { pcm { @func concat strings [ "cards.EMU10K1.pcm.rear.0:CARD=" $CARD ] } channels 2 } ] bindings [ { slave 0 channel 0 } { slave 0 channel 1 } { slave 1 channel 0 } { slave 1 channel 1 } ] } <confdir:pcm/surround41.conf> <confdir:pcm/surround50.conf> <confdir:pcm/surround51.conf> EMU10K1.pcm.surround51.0 { @args [ CARD ] @args.CARD { type string } type multi slaves [ { pcm { @func concat strings [ "cards.EMU10K1.pcm.front.0:CARD=" $CARD ] } channels 2 } { pcm { @func concat strings [ "cards.EMU10K1.pcm.rear.0:CARD=" $CARD ] } channels 2 } { pcm { @func concat strings [ "cards.EMU10K1.pcm.center_lfe.0:CARD=" $CARD ] } channels 2 } ] bindings [ { slave 0 channel 0 } { slave 0 channel 1 } { slave 1 channel 0 } { slave 1 channel 1 } { slave 2 channel 0 } { slave 2 channel 1 } ] } <confdir:pcm/iec958.conf> EMU10K1.pcm.iec958.0 { @args [ CARD AES0 AES1 AES2 AES3 ] @args.CARD { type string } @args.AES0 { type integer } @args.AES1 { type integer } @args.AES2 { type integer } @args.AES3 { type integer } type hooks slave.pcm { type hw card $CARD device 2 } hooks.0 { type ctl_elems hook_args [ { name "IEC958 Playback Default" lock true preserve true value [ $AES0 $AES1 $AES2 $AES3 ] } { name "IEC958 Optical Raw Playback Switch" lock true preserve true value [ 1 1 ] } { name "SB Live Analog/Digital Output Jack" lock true preserve true value 1 } ] } } |
