Alas, the new VIA82XX.conf doesn't fix the problem. (ALC655 does not have the "Slot Modify" feature of ALC650). Also I realise I still need a plug with slave.channels 6
If I use surround51 directly I cannot get sound out of the other four speakers. This plug gives me rear sound
pcm.testrear {
type plug
####Aargh!! should be ttable.0.2 and ttable.0.3####
####Changing Swap Surround Slot doesn't help###
####ALC655 does not have Slot Modify control bits in register 6A###
ttable.0.4 1
ttable.1.5 1
slave.pcm surround51
slave.channels 6
}(I notice surround50.conf has the slave channels set; can something similar be put inside surround51.conf?)
xine will also not product surround sound with the surround51 device - I need to use a plug with channels set to 6.
Funny though mplayer works with the surround51 device (though channels are swapped).

I've finally got 5.1 out of my via82xx/ALC655 system using the Line-In/Mic jacks!
Thanks Takashi.
glad to hear that it works now. what was the problem?
However I seem to have got Center/LFE switched with Surround.
I.e. if I play xine & mplayer (L, R, RearL, RearR, Center, LFE)
through surround51 I get Center/LFE switched with Rear speakers.
ah, this reminds me an old story. there is a mixer switch "Swap Surround Slot". and, IIRC, starngely enough, for 5.1 this should be turned on for 5.1 output while it's off for 4.0.
I must use the following to work in .asoundrc pcm_slave.sltest { pcm "hw:0,1" channels 6 }
pcm.via51 {
type plug
ttable.0.0 1
ttable.1.1 1
ttable.2.4 1
ttable.3.5 1
ttable.4.2 1
ttable.5.3 1
slave sltest
}
this is also a solution, but the attached would be more "light" way. copy the attached file to /usr/share/alsa/cards. also, if you have chance, please test 4.0 output, too.
thanks,
Takashi
