Title: Bitstreaming question wrt to FLAC and ALAC
Post by: davidw55 on June 27, 2019, 01:59:01 pm
Hi

Running MC 25 Linux sending audio out via HDMI to a receiver.

My receiver supports FLAC and ALAC (and a few others) up to 192khz sampling.

I've noticed that no matter what I do, the receiver reports PCM is coming from MC.  I've enabled bitstreaming as an experiment.   I looking to see if MC, when acting only as a renderer, could just send the data to the receiver without change.

Now, another instance of MC is acting as the server, but I believe I've told that server to not convert or resample anything.

(I'm aware of the advice re:bitstreaming, that MC probably does a better job of handling DTS and Dolby Digital than the receiver)

IIRC, bitstreaming over HDMI isn't supported in Linux, I think Hendrik made a comment on this earlier.

Since you mention FLAC and ALAC, it should also be noted that those formats cannot be bitstreamed at all, since the HDMI specification does not include such audio formats.

Ok so, over HDMI, MC users should expect to see only PCM.

Thank you.
