I don't have any particularly concrete ideas because the error log isn't very descriptive, but I have several things you can try that will give us more info/may help pinpoint the issue.
You might want to post the contents of your /etc/asound.conf and your ~/.asoundrc as well as maybe checking the contents of /usr/share/alsa if there's anything still referencing pulseaudio in there. Maybe also a qcheck media-libs/alsa-lib to check if any of the default config files have any changes in them (you can also diff the output of qlist alsa-lib and find /usr/share/alsa). You might also want to check your mpv.conf if you have change any of the audio settings there.

You could also try setting --audio-samplerate=48k and try enabling/disabling alsa resampling with --alsa-resample=yes/no.

What samplerate does that generate sound at? 48k or 44.1k? -- Simon Thelen
