I think it’s mostly a ArchLinux issue since the pulseaudio-alsa package isn’t installed by default. Installing it fixed the issue for me. Just followed the instructions here: https://wiki.archlinux.org/index.php/PulseAudio#ALSA
It’s still kind of bug. osu shouldn’t be using ALSA directly. ALSA can only have one audio source at time. What osu is trying to do here is to take full control of the selected sound card. If another program is already using this card (pulseaudio) it fail and give this
error: ALSA lib pcm_dmix.c:1075:(snd_pcm_dmix_open) unable to open slave
. The pulseaudio-alsa package is a workaround that route ALSA audio to Pulse. A real fix should be to add PulseAudio support in osu.Ok, after seeing this post : https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=913045 I fixed it by creating the
~/.asoundrc
file with content :(and then rebooted) Note: it’s also doable system wide, but I didn’t test that option yet.
Could be useful for anyone else having this issue, but I guess it’s more of an ALSA or archlinux issue (wrong defaults ?) than an osu!lazer issue.
Sorry for the annoyance, but at least I guess this issue can be closed ?
