MPRIS error

[flg]

After moving from CentOS 8 to CentOS Stream 8 (can't tell if it's related or not), I get this error:

cmus: Error: an error occured while initializing MPRIS: Invalid argument. MPRIS will be disabled.
cmus: Press <enter> to continue.

Dbus is running. DBUS_SESSION_BUS_ADDRESS is properly set in the environment.

I too get this cmus: Error: an error occured while initializing MPRIS: No medium found. MPRIS will be disabled. error in arch wsl 2

I may be getting a similar error, with cmus: Error: an error occured while initializing MPRIS: File Exists. MPRIS will be disabled.
On top of that cmus can no longer play music. Hitting enter on a track will mark it as playing but it will be stuck at 00:00. Seeking through the track will update accordingly but the music will still not play. Hitting c during this point will cause it to crash and requires it to be manually killed.

My other commands are identical to that of the OP.

I was having the same issue on Void Linux. However, I was able to resolve the issue by editing the autosave file. I should note that I am using PulseAudio, and the default configuration was set to use ALSA, so changing those settings in addition to disabling MPRIS seemed to fix it. I'm using cmus v2.9.1

The file is located:
~/.config/cmus/autosave
I changed the following settings to:
set mpris=false
set dsp.alsa.device=
set mixer.alsa.channel=
set mixer.alsa.device=
set output_plugin=pulse
After changing these settings, cmus began to work as usual. Hope this helps!

@Koshkov Disabling mpris via the autosave file does indeed make the error disappear. It does not solve the original issue that MPRIS is not working whereas it should.

Seeing this on the Flathub package.

Same issue on FreeBSD current.
