- power saving functions
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.
Well, if it was its own subdevice like hw:0,2 it would have some hope of being detected by HAL, PulseAudio, etc. If it's just a substream then I don't think that software can actually tell it's a separate output and not just a HW mixing-type stream, etc.
Right, that's the missing information.
Hopefully VIA will also look into the SPDIF no-output problem I have with VT1828S..
What is the problem, specifically?
With the latest patch I do get the optical output lighting up and the receiver detects a PCM signal, but it seems to be just silence coming through. (In previous iterations the SPDIF digital converter wasn't being enabled automatically so it didn't get even that far.)
You can fiddle with hda-verb to issue digital-converter verbs. Possibly you need to flip the digital-enable bit to send the values...
thanks,
