Reproduction Steps

1. Configure MPV to bitstream atmos with audio-spdif=truehd
2. Open a file with an dolby atmos track like this: https://www.demolandia.net/downloads.html?id=47981918

Expected Behavior

The audio is played without errors

Actual Behavior

I have a dolby atmos system with upfiring speakers so i want to bitstream dolby atmos directly to the system but:

There are reoccuring audio dropouts. They last around 1 second each.

First i thoughts its a hardware problem but then I played the same files with vlc and there are no audio dropouts at all. So it has to be a problem with mpv.

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.
