Hi list,

I am trying to work around a problem that I have not experienced in the
past (but I can not trace it down to a specific package upgrade):

mplayer and mpv both crash when playing back audio files of varying
formats (wav, ogg, etc) which have a different sampling rate than jack
(tried with both jackd1 and jackd2). The files play fine when using alsa
as audio output driver.

A gdb backtrace points to usr/lib/x86_64-linux-gnu/libswresample.so.3
which is from Debian's package libswresample3 of version
7:4.3.5-0+deb11u1
I can not downgrade this package to the only other available version
(7:4.1.9-0+deb10u1) without removing most of my audio programs.

Is this error known? How can I find out more about it, and how could I
possibly fix it?

Thank you!
Peter

I can't help you with your problem but can say I don't have the problem here.

$ apt list -i libswresample3

libswresample3/stable,stable-security,now 7:4.3.5-0+deb11u1 amd64 [installed,automatic]


Playing 2 files I just ripped from vinyl and restored in iZotope RX in Windows, one 24/96, the other 24/44.1 :

$ mpv --ao=jack *.wav
Playing: Blue Monday-24-96 RX-fin-dithered.wav
 (+) Audio --aid=1 (pcm_s24le 2ch 96000Hz)
AO: [jack] 48000Hz stereo 2ch floatp
A: 00:07:35 / 00:07:36 (99%) Cache: 0.0s

Playing: The Beach (12inch single)24-44.1-dithered.wav
 (+) Audio --aid=1 (pcm_s24le 2ch 44100Hz)
AO: [jack] 48000Hz stereo 2ch floatp
A: 00:03:36 / 00:07:24 (48%) Cache: 227s/64MB


Wish you luck. Let me know if there are any more tests I can run for you.

Cheers, Roger
