ALSA function 'snd_pcm_hw_params' failed with error 'EIO: I/O error'

[tranxuanthang]

I am facing this error on Arch Linux (KDE Plasma 5 on Wayland). I did not know what when wrong, and I cannot reproduce when using symphonia-play (the song still played as expected). Please let me know if you need any additional information.

Step to reproduce:

git clone git@github.com:tesselode/kira-examples.git
cd kira-examples
cargo run -p simple-sound-playback

Looks like running pacman -Syu AND restarting the PC fixed it for me!
