I believe you should disable resampling for DSD to work. You can see from the log file that ALSA is first opened for dsd but then it falls back to pcm due to resampling.

Emilot commented 3 months ago

I agree but where is resampling enabled?

it has # to all resample block (here as i see is with bold letters but it is there in mpd.conf)

MaxKellermann commented 3 months ago

You can't enable resampling, the hint was wrong. MPD will resample only if you tell it to or if it is necessary.

You are trying to play a DSD64 file but your DAC is incapable of doing that; the best appromixation your DAC allows is DSD32. MPD even explained that to you in the error message, didn't you see that?

This problem is in your DAC, not in MPD.

Hmmm....

Nope. DAC can play up to 512DSD.

This is the correct data. All i was did is to disable "thesycon_dsd_workaround" option.

So i guess is your turn now Max.

Thanx!

Emilot commented 3 months ago

Please re-open this issue Max and let me know if you need from me to provide anything else...

Thank you

MaxKellermann commented 3 months ago

No, there's nothing to discuss here. MPD is working as designed, and you did not provide any data that demonstrates otherwise. Now please stop spamming me here.
