Play DSD on Raspbian issue #796

Open starmood opened 4 years ago

starmood commented 4 years ago

Bug report

Describe the bug

If enable FIFO output, when start playing DSD file there will be some 'click' noise for standard Alsa output during first 5 or 10 seconds, sometimes the sound will break for like 0.1 second. If disable FIFO output, then no such issue. I also tried with older version, like 0.21.16, there is no such problem. My test platform is Raspbian Buster 2019-09-26.

Is your CPU overloaded? If other processes take away CPU time from MPD, it could be useful to fix the real-time scheduling problems first. See the warnings in your log?

starmood commented 4 years ago

CPU is not overloaed. FIFO thread keeps ~ 20%.

I will take a look at RT error tomorrow. But actually if I switch to 0.21.16, same RT scheduling error is also in the log, but there is no DSD playing issue.

starmood commented 4 years ago

I used systemd to start the mpd, now RT scheduling error is gone. But the problem is still same.
