For the records, the Alesis io2 Express appears to work fine under
OpenBSD. The device has 2 channels, for each channel line out,
line in and mic in are working properly (I did not test the insert
jack and midi connections, but the latter do appear in dmesg). Headphone
out works great too, but the mono/stereo switch does not have any
effect. The monitor mix knob (direct/usb) also functions correctly.
So far I'm very happy with this usb soundcard under OpenBSD, big thanks
to the devs!
dmesg and audioctl output is attached below. There are no mixerctl
variables.
