Thanks for the patches. They are all well formatted now.
I applied your patches except for 17, ALSA: HDA VIA: Add 2nd S/PDIF out for VT1708S and VT1702 as Robert reported a regression.
This is likely because of the behavior change by this patch. Now the second SPDIF has to be specified manually with the explicit substream number. This itself is fine, but I see the problem with pulseaudio, for example. There is no good way to specify this substream automatically for PA with some symbols like "spdif" or "hdmi".
This is basically a problem of the current ALSA core and HD-audio core implementation. So, we should solve all together.
Actually, the latest posted version didn't have the mixer problem I had before (I haven't looked in detail at what was different). But I agree using a different substream for a different output isn't ideal since there's no way for software to detect that this is the case. Can it be a separate PCM like hw:0,2 or something?
It would work like hw:0,1,1. But, this is exactly what I mentioned in the above. The secondary SPDIF isn't specified as an intuitively selectable PCM device.
Hopefully VIA will also look into the SPDIF no-output problem I have with VT1828S..
What is the problem, specifically?
thanks,
Takashi
