As one needs output in both, I tried to use .asoundrc , and therefore needed to use the "multi" pcm type in order to unite these two (and then route). This is what I put in .asoundrc pcm.whole { type multi slaves.a.pcm "hw:0,0" slaves.a.channels 2 slaves.b.pcm "hw:0,4" slaves.b.channels 2 bindings.0.slave a bindings.0.channel 0 bindings.1.slave a bindings.1.channel 1 bindings.2.slave b bindings.2.channel 0 bindings.3.slave b bindings.3.channel 1 } pcm.rt { type route slave.pcm "whole" ttable.0.0 1 ttable.1.1 1 ttable.0.2 1 ttable.1.3 1 } The ttable may be wrong - I could not find a sane description anywhere - but I tried many variants, and besides, playing to "whole" bypasses this. So here's what I get when playing to "rt" OR to "whole" via alsaplayer : $ alsaplayer -d whole test.wav error on set_channels (2) Unavailable hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 64 CHANNELS: 4 RATE: 44100 PERIOD_TIME: (181 371520) PERIOD_SIZE: [8 16384] PERIOD_BYTES: [64 131072] PERIODS: [1 1024] BUFFER_TIME: (181 371520) BUFFER_SIZE: [8 16384] BUFFER_BYTES: [64 131072] TICK_TIME: 1000 error on set_channels (2) Unavailable hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 64 CHANNELS: 4 RATE: 44100 PERIOD_TIME: (181 371520) PERIOD_SIZE: [8 16384] PERIOD_BYTES: [64 131072] PERIODS: [1 1024] BUFFER_TIME: (181 371520) BUFFER_SIZE: [8 16384] BUFFER_BYTES: [64 131072] TICK_TIME: 1000 failed to configure output device...trying OSS then alsaplayer hangs until interrupted. When I comment out everything related to slave b, "whole" seems to work (without spdif output, of course). So this seems like a bug in the spdif device. ====================================================================== ---------------------------------------------------------------------- tiwai - 10-08-2004 12:13 CEST ---------------------------------------------------------------------- Use this: pcm.rt { type route slave.pcm whole slave.channels 4 ttable.0.0 1 ttable.1.1 1 ttable.0.2 1 ttable.1.3 1 } and run with -d rt . ---------------------------------------------------------------------- ramendik - 10-08-2004 12:29 CEST ---------------------------------------------------------------------- Thanks. This has worked. A definite must for the FAQ, and a link to this should be present in the soundcard matrix for i865 - which at this point is not even available. But I'll refile this as a documentation bug. Please close this one. Actually, the absence of a *decent* documentation of the route type is another documentation bug. And, as a professional tech writer I'm qualified to fix this. I'll write to alsa-devel to offer my services. ---------------------------------------------------------------------- tiwai - 10-08-2004 12:42 CEST ---------------------------------------------------------------------- Yes, we know the documentation problems :-< Any help would be appreciated. BTW, it's possible to implement the analog and spdif simultaneous output on ICH4 without data duplication. I'll try a hack later. Anyway, I close this bug now. ---------------------------------------------------------------------- tiwai - 10-11-2004 15:39 CEST ---------------------------------------------------------------------- Could you try the attached patch? With this patch, the signal to hw:0,0 will be routed to the spdif, too. This behavior should be switched by either a module parameter or a mixer control because someone may want to use analog and SPDIF separately to play different streams.
