High-res songs skipping after 50-ish seconds

[ajudge00]

My setup is this:

1. My phone has a UPnP control point app. Its source is my NAS (zyxel).
2. The phone's output device is a mini-PC running MPD and a tool called upmpdcli in Ubuntu.
3. Upmpdcli receives what to play from the phone and it plays. Nice.

Problem:
Some higher res songs (192kHz/24bit flac's) skip after 50 seconds. The song starts properly, plays properly, but skips to the next track after 50 seconds.

What I did was change MPD's buffer settings, namely
audio_buffer_size
buffer_before_play
connection_timeout
max_playlist_length
max_output_buffer_size

I set these to pretty high values (65536-131072 range) and it did improve the situation... well, 50 seconds is the best result yet, at first the skip happened after 10...

I also checked memory usage limitations, no issues should be there. What am I doing wrong?

Note though that upmpdcli is not an application that can be supported by this project. We can help only if this is unequivocally an issue caused by MPD, unrelated to upmpdcli. To find that out, you should play the very same file locally, i.e. without streaming and without upmpdcli.

I have a mpd satellite setup and meet the similar problem. When I play 24bit/192kHz music files whose sizes are easily over 200MB, mpd at the satellite will skip to next track before the current track is finished. If I check the systemd status of mpd, I will see an error message "exception: CURL failed: A value or data field grew larger than allowed". I tried to set input_cache to 500MB at the satellite but the problem remained.

Attach here mpd.conf at the satellite:

playlist_directory`  "~/.mpd/playlists"
music_directory  "http://nas.home:8888"

bind_to_address  "localhost"

database {
  plugin  "proxy"
  host  "nas.home"
  port  "6600"
}


audio_output {
  type "pipewire"
  name "pipewire audio server"
  enabled "yes"
  dsd  "yes"
}

This sounds like a known CURL bug that many MPD users have experienced.

Thanks for the reply.
You are right. I just switched to nfs and the problem has gone. I only changed the music_directory to

music_directory "nfs://nas.home/media/music"
