Thanks to Jonas and Curt for your replies, both of which helped me to resolve this issue. I had never thought of running MPV from the commandline, I'd always just right-clicked the programme that I wanted to watch and never considered the command-line option. and when i did run it from the line it consistently showed as part of its output when running - mpv -v /mnt/backc/progs/Our_Lives_Series_3-Series_3-Mountain_Rescue.mp4 - --8<---------------cut here---------------start------------->8--- [ad] Selected codec: aac (AAC (Advanced Audio Coding)) [lavfi] filter 'drc' not found or failed to allocate [user_filter_wrapper] Creating filter 'drc' failed. [cplayer] Audio filter initialized failed! --8<---------------cut here---------------end--------------->8--- But when I looked closer at the output in my terminal I found this - [cplayer] Reading config file /home/boudiccas/.mpv/config - which was what I was expecting, but that config file only showed '# Write your default config options here'. And further down the output it showed - '[cplayer] Reading config file /home/boudiccas/.config/mpv/mpv.conf'. This was a revelation to me as I was totally unaware of this file, and in its 'audio section' it showed several uncommented items, so I commented them all out and tested MPV again. And it worked, I had sound again! Thank you very much, I'm a happy bunny again! :) Jonas Smedegaard <jonas@jones.dk> writes: > Quoting Sharon Kimble (2019-07-10 12:13:30) >> >> Ever since upgrading to buster I've been completely unable to get any >> sound out of MPV.
