I know this has been discussed extensively on this forum and elsewhere but I haven't gotten any sufficiently resolving answers anywhere. The consensus seems to be that setting the Airplay receiver as the system output on a Mac allows for transmission in ALAC, and I was operating under this assumption for the longest time. But I could always hear the reduction in bitrate when compared to local Flac files, which shouldn't be the case for 16/44.4 files.
I checked my network monitor, and AirplayXPCHelper is only uploading at up to 140 KB/s. If this is the streaming speed, it is extremely unlikely to be lossless.
Is Shairport on moode compiled with the --with-alac flag? Does anyone know any more about getting lossless working with Shairport?
This is a really important use-case for me. Sorry if this question has been beaten to death, I just need a more knowledgeable other to hold my hand with this a little bit.
I have read on another forum, where AirPlay 2 is also under scrutiny, the following:
Quote:Yes, AirPlay (1 and 2) does support lossless, it's actually Apple that is limiting it to AAC with AirPlay 2 to focus on one of it's intended purpose: multi-device listening with Apple Music. It want to save bandwidth, but they should give us options to bypass but knowing Apple if they give you something you have to do it their way.
It could be not, but also there, people is complaining about seeing AAC only, and at low bitrates; looks too coincidental to me...
If I get some time I can try some tests later on.
