Note: this issue has the same symptom as #11790, but is not fixed with --ao=pulse and only triggers when displaying the stats screen.

Reproduction Steps

Make sure client-rt.conf is absent from the system. I don't know where libpipewire looks for it, so ideally reproduce this on a system without any pipewire components except libpipewire itself.
Play any media file or stream with --ao=pulse --no-config. I was reproducing the issue with an ogg audio file and --no-video
Press i to trigger the stats screen.

Expected Behavior

The stats screen is shown:

 (+) Audio --aid=1 (vorbis 2ch 48000Hz)
AO: [pulse] 48000Hz stereo 2ch float
File: audio.ogg
        Size: 6.380 MiB  Format/Protocol: ogg
        Total Cache: 57.28 KiB (1.0 sec)

Audio: Vorbis  AO: pulse
        Device: Autoselect device  AO Volume: 100% (Muted)
        Channels: 2  Format: floatp ➜ float
        Sample Rate: 48000 Hz
        Bitrate: 187 kbps
A: 00:00:01 / 00:04:37 (1%)

Actual Behavior

Two pipewire warnings are printed (also mangling the terminal display) along with the stats screen:

 (+) Audio --aid=1 (vorbis 2ch 48000Hz)
AO: [pulse] 48000Hz stereo 2ch float
A: 00:00:03 / 00:04:37 (1%)[W][09477.196660] pw.conf      | [          conf.c: 1175 try_load_conf()] can't load config client-rt.conf: No such file or directory

File: audio.ogg
        Size: 6.380 MiB  Format/Protocol: ogg

Log File

Note: I press i on line 190 output.txt

Sample Files

No response

I carefully read all instruction and confirm that I did the following:

[X] I tested with the latest mpv version to validate that the issue is not already fixed.
[X] I provided all required information including system and mpv version.
[X] I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
[X] I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
[X] I attached the full, untruncated log file.
[X] I attached the backtrace in the case of a crash.

this on a system without any pipewire components except libpipewire itself.

This isn't a valid pipewire installation according to upstream, the config files need to be installed together with libpipewire.

pipewire requires that the config files be present on the system. If client-rt.conf doesn't exist on your system, report it to your distro.

I see. I will do that.

Update for fellow Debian users: looks like this bug is already tracked as #1038394 on the BTS. Installing pipewire-bin seems to be a working workaround for mpv without installing the entire PipeWire metapackage.
