Reproduction Steps

1.) Insert CD (reproducible on my end with any Audio CD I tried, both burned and original)
2.) Play with mpv cdda:///dev/sr0

Expected Behavior

No noise, sound quality equivalent to VLC (tested on the exact same hardware)

Actual Behavior

Annoying noise in the audio

Log File

output.txt

Sample Files

No response

I carefully read all instruction and confirm that I did the following:
  • I tested with the latest mpv version to validate that the issue is not already fixed.
  • I provided all required information including system and mpv version.
  • I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
  • I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
  • I attached the full, untruncated log file.
  • I attached the backtrace in the case of a crash.

Research direction

Reproduce the issue from the documented entry point, mpv cdda:///dev/sr0, using the ASUS DRW-24D5MT and the attached output.txt log as the starting evidence. Compare playback with VLC on the same hardware, then verify that Audio CD playback is free of the reported noise and retains equivalent sound quality.
