Hi, mixerctl is still the appropriate tool here, sndioctl is not inteded to be run as root. usbhidaction runs as root, given /dev/uhidN permissions, it's clearly not intended to run "high level" user commands. For instance it makes no sense to run "audiocious -u" when Pause/Play key is hit, it's the similar for sndioctl. The mixerctl utility remains for such "low level" use cases. Any program using sndiod is intended to be used one user at a time for obvious privacy reasons, this is quickly explained in the last section of sndio(7).
