ALSA driver not found

I have very bad sound quality when using musescore with Pulseaudio, lots of cracking, noises and distortion.
I would like to use ALSA instead because I know from earlier experience that this used to work fine on my system. But when i switch to ALSA in the I/O settings window I get no sound at all with this output in the terminal:

Alsa_driver: the interface doesn't support mmap-based access.
ALSA lib seq_hw.c:466:(snd_seq_hw_open) open /dev/snd/seq failed: No such device
init ALSA driver failed
no audio driver found

I am using Manjaro (Archlinux) and don't have any sound issues with other applications.

Does something happen when you change the device in preferences-> I/O from "default" to "hw:0" (and restarting MusScore)?

It seems there was something wrong with my latest update to ALSA 1.1.4
I reinstalled the relevant packages and now it works again. I only get

AlsaDriver::write: snd_pcm_avail_update() (Broken pipe)
AlsaDriver: recover: stat = 00, xrun of at least 307.745 ms

Is this normal?
