I bought used TASCAM US4x4
It just works - and that is great. There're some issues:
- cracking noise during CPU / IO intensive tasks running on PC
- a glitch on first use in every session
but these I already read about when doing my research before the purchase
More immediate and pressing issue is that I cannot control this card with alsamixer / amixer.
Alsamixer, after updating to the latest kernel, says "This device does not have any controls"
So I don't have a programmatic master volume control.
I configured softvol plugin, but it works with delay.
I read about alsactl somewhere, ran "man alsactl" and read this: "If your card has features that you can't seem to control from a mixer application, you have come to the right place"
Not sure if it applies to this case, but I wanted to try to store settings, update them and load back to card. But alsactl store always saves controls of ALL available sound cards (and that's A LOT of conrols)
