Local video buffering

Reproduction steps
Just playing video from a hard drive
Actual behavior
At random points in playback, video starts to lag as if it were buffering (video is locally stored), after several seconds it plays normally again. This seems to happen when audio is eac3.
Log file
I was trying out different options and was getting following message:
[cplayer] Audio device underrun detected.
[cplayer]
[cplayer] Audio/Video desynchronisation detected! Possible reasons include too slow
[cplayer] hardware, temporary CPU spikes, broken drivers, and broken files. Audio
[cplayer] position will not match to the video (see A-V status field).
But that was a while ago and I can't remember which option made this message show up, without any options behavior is the same (buffering) and whole log can be found here: https://0x0.st/ovjI.log
When message above was issued there were no CPU spikes (at least nothing that htop showed), files aren't broken either - I could play them fine on a different machine.
Sample files
The video is quite large, around 5Gb, I'm not sure where I could upload it
I wonder if that's related to https://github.com/mpv-player/mpv/issues/10290.
I have recently noticed the same kind of hanging I had in the issue above when I activate a noise gate, but I haven't looked into it so far.
Apparently the issue was that the video I was playing was on an external HDD connected through USB 3.0, moving files to internal HDD fixed the issue, although I'm not entirely sure of the root cause - slow USB or HDD speed?
