Audacious - OLD, PLEASE USE GITHUB DISCUSSIONS/ISSUES

Here's a backtrace I got when I double clicked on a song in the list to jump to it:

Based on the backtrace, this looks more like a problem in PulseAudio or possibly even X11 than in Audacious.

For a workaround you could use ALSA output.

Just changed to ALSA output in Audacious preferneces and got same result with different backtrace:

joe@ghubuntu1:~$ audacious
alsa: snd_pcm_recover failed: Input/output error.
alsa: snd_pcm_recover failed: Input/output error.
alsa: snd_pcm_recover failed: Input/output error.

Try running Audacious in Valgrind to see if it can pick up any errors.

Well, you have three apparently unrelated crashes here. I'm afraid I can't be of any more help without being able to reproduce any of them. Let us know if you find out the cause.
