Hello, While sample rate + bit depth switching support via lightning to DAC via the USB dongle has been supported on iOS for some time in applications such as VLC and Tidal, it has now also officially come to Apple Music. Considering Plexamp already supports showing the “codec” flags of the track …

I am sort of achieving this by selecting my DAC as my Plexamp output device, but then switching the rest of system audio [macOS FWIW] to a different output device like internal speakers.

[image] fjen: My understanding is that no “support” is needed from the software player if the first “unfold” is not handled by the player I would agree; in practice I couldn’t find any cheap DACs which handled the first unfold :sweat_smile:

Khadas Tone 2 Pro would be a good example. :blush: Though potential 16-bit LSB bit-perfect would still be nice for those of us with higher end MQA Full Decode + Render DAC’s. :pleading_face:

Well, let us know if it works :sweat_smile: I refer to it as “bit-perfect-ish”. Might be good enough to turn lights purple, I just don’t know. You’d of course have to turn off loudness leveling, sweet-fades, EQ…

I’m interested to know quite what “bitperfect-ish” means :slight_smile: Any indication of timelines for all this? It’s all sounding good for improving plex as an audiophile music server platform.

okay, so I saw this pic on reddit and wanted to flag it here as I’d really love to see something in future plex/plexamp that allows the user to understand that they are or are not getting the full benefit of any HD audio files they have. Oftentimes it can be hard to tell from the equipment and havin…

Looks like it’s in, but not perfect yet. It’s a little too cumbersome to record but there are instances where it doesn’t switch sample rate and they don’t appear to be random. I have two albums by Beach House that are at 48/24 and tracks from one will switch my DAC (SMSL SU-9) to 48k and one will no…

Thanks very much for implementing this! I’ve just spent 5 mins testing on an M1 ipad pro, using a chord mojo dac. I’ve loaded up a number of songs and I’ve certainly seen the sample rate switching, but I’ve also noticed a couple of times it ends up getting stuck at a particular samplerate and then …

[image] fyonn: no matter what you play, it enters the DAC at that rate. so far I’ve seen it on a 96khz track and on a 44khz track After stopping playback? Or are you queueing up new tracks during playback. Remember, the switching only occurs opportunistically.
