(12-29-2023, 10:36 PM)Thanks a lot for the comprehensive reply! I believe MDP is not involved when tidal connect plug-in is working... thus agree the solution should come from the DAC driver. I connected my DAC with 3-wire I2S, and device driver operating for it is RPI-DAC recognized by aplay -l as bcm2709. I\d need to modify the driver's code and re-build it for my device - but, honesty, looking for some ready-made solutions if availably ... :) Wrote:(12-29-2023, 09:31 PM)Tim Curtis Wrote: The symptom suggest an issue in the Tidal Connect add-in. You could try contacting the maintainer of the Git repo but due to the nature of the code the repo may not accept issues.
The problem is more likely to be intrinsic in the (some, not all) DAC: when the bitdepth/samplerate changes between tracks, the DAC closes the stream => reconfigures it => opens the stream; and this produces the annoying clicks/pops.
You should experience the same problem if you play local tracks with different bitdepth/samplerate (provided MPD does not do some magic).
Can you try, just to be sure it is, or not, a Tidal-only problem?
For what I have been reading in the forums there are different solutions, like:
1. telling the DAC to keep the stream open (this is done via the driver, in Win environments)
2. muting the DAC when necessary
3. telling the DAC also "what comes next" (again, I think this is driver-related in Win environments)
Since MPD is not involved in the specific process (in this case streaming from Tidal) I believe it would be impossible to determine:
1. when a stream is close to its end
2. what the parameters of the new stream are *before it begins*
3. trigger some action in order to, at least, mute/unmute the DAC
I stand to be corrected, especially about MPD being or not part of the chain; nevertheless, even if it is involved, I doubt it can let us know what it is about to play next.
Assuming it is, we could eventually know when the stream ends, and trigger the MUTE/UNMUTE event unconditionally, but this would, at least. break the gapless playback, IMO (and this would be unacceptable, at least for me).
What DAC is it? Does it offer some configuration? What is this "direct driver mode", something specific to it, or moOde related (yep, I have no clue...)
Have you done some research on the relevant forums, about this issue?
