gentoo linux, no desktop audio

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.
