Description of Issue
Hi all… I have a wide variety of different formats in my library. Everything from DSD256 and FLAC 192/24 all the way down to MP3 320. My listening chain is mostly direct-attached storage, with occasional QoBuz through CoreAudio to my CAD DACMAGIC 200M.
Playing any playlist and mixing formats used to be perfectly smooth. Sometime in the last month or two, everything kinda went to hell. Almost every time I switch between audio formats, one of a few things will happen:
The audio device will fail to initialize (see screengrab here…)
The connection will drop to the DACMAGIC. (screengrab…)
Or the most fun one… everything seems fine, but the audio is clearly playing at the wrong speed. It’s like a 96 file is playing at 44.1 speed, and is slowed down by half. This is happening right now as I’m listening, and Roon is reporting all is well. (screengrab of listening chain…)
This never used to happen. And I’ll be honest, no idea if this is because of a Roon update, or a MacOS update, or some combination. But it has removed my ability to listen to an actual playlist, because every track that is a different format… something like this happens.
This happens when going from local file → local file, or local file <-> QoBuz. It doesn’t seem to be related to a networking issue, as it never happens when going from files that are the same (i.e.: 96/24 to 96/24) - only when a new format is encountered.
When this happens, fyi, the front lights on the DACMAGIC indicate that a new format is seen, i.e.: front panel does switch from 96 to 192 (or whatever).
