Whereas lspci shows Audio device: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller (rev 04) Manual says it’s Realtek ® ALC892 8-channel High Definition Audio CODEC.Īplay -l shows it as card 0: PCH, device 0: ALC892 Analog I use desktop computer with Asus motherboard’s integrated audio. I do use a rather crude workaround for this with alsamixer – but it’s rather clumsy and switches between outputting sound to both devices simultaneously or headphones only – not an elegant solution. I’ve searched for solution for some time but couldn’t find anything good. I think I’ve seen them as separate devices on older (not recent) versions of Fedora as well but I can be mistaken here. I have to say that Windows does show speakers and headphones as separate output devices and allows switching between them easily – so I’m quite sure the same can be achieved in Linux. I don't know the parts off hand, but they weren't that expensive and were readily available.I know that sound output switching works ok when I physically remove/connect my headphones, but is there a way to achieve the same without unlugging anything? You can send the analog stereo mix into Zone B of your receiver, while maintaining synchronized playback and discrete 6 channel audio audio in your main zone. It was feeding older bluetooth speakers that didn't have AptX low latency support, and the BT transmitter didn't support this either, so while it worked, the audio coming out of the bluetooth speaker in the kitchen was delayed.īut for you, you won't have this problem. The second went into a DA box that was set to accept DD 5.1 and downmix it to stereo.įor me, that stereo downmix analog output went to a bluetooth transmitter, and it never worked properly because of latency introduced in this step. It duplicates the optical output to two optical cables. I configured MPC via LAV audio filter to transcode all to Dolby Digital 5.1 as well, and just hand over Dolby Digital streams natively. So I configured my NUC to output only on optical, and forced the output to 5.1.
There is software that does this, not sure what it is, but I know it exists, but I worked out a solution for part of this in my HTPC.įirstly, my HTPC connects to an obsolete receiver that only has toslink and dolby digital.
