3 years ago Which libnfs version?
a-dekker
commented
3 years ago There is an issue with libnfs in combination with certain recent 5.10.x kernels on the nfs server side that should be solved in kernel 5.10.15. It also effects my kodi video playback via libnfs (stuttering, skipping parts), although music playing music still seems okay. Using a regular mount solves this.
See for example https://github.com/xbmc/xbmc/issues/19147
Not sure if this is related, but I would check before diving deeper in mpd itself.

3 years ago libnfs version: local/libnfs 4.0.0-4 kernel: 5.10.8-arch1-1. I can report back when I've upgraded to the latest kernel.

3 years ago Issue still present on kernel 5.11.1-arch1-1, libnfs unchanged, mpd now version 0.22.6-1

3 years ago NFS server upgraded to 5.10.16 fixed playback via MPD, i.e. the configuration above:
music_directory "nfs://192.168.0.101/export/Music/Library"is now working for playback, so this issue can be closed.
Bug report
Describe the bug
When decoding music files from an NFS store audio becomes choppy after a few seconds, and skipping fails to work. The issue is not seen when the system's mountpoint of the NFS store is used. This issue may be related to #779 , however I am running Arch Linux rather than a Windows host. I have also experienced #1054, however this bug is over NFS rather than SMB.
Expected Behavior
Audio plays as expected, with no glitches. When the music directory is set to the mountpoint of the NFS share by the system, MPD functions correctly. Example
~/.config/mpd/mpd.conf, in which audio works correctly:Actual Behavior
When the NFS mount is instead specified in
~/.config/mpd/mpd.conf:decoding errors occur after a few seconds. These errors are independent of filetype, and as the only change in configuration options is the addition of nfs it seems this may be the issue.
