描述

when trying to use the desktop player, i get an error saying "Unable to create audio device: A backend-specific error has occurred: ALSA function 'snd_pcm_start' failed with error 'EPIPE: broken pipe'"

i'm not very experienced with rust, but i was able to find where the error's thrown using a lot of println statements. in desktop/src/audio.rs, on line 108, there's a block of code that starts with "match sample_format" and none of my printlns after it show up, but all the ones before do.

研究方向
Investigate the ALSA audio backend in desktop/src/audio.rs, particularly around line 108 where the sample format match occurs. The error 'EPIPE: broken pipe' suggests a device initialization or timing issue. Check if the device is properly configured before playback starts, and review any comments in the issue for additional context. Also consider if the code needs to handle the broken pipe error by retrying or resetting the device.
