Perhaps I need to patch something manually?
Is this about having 4 playback ports on the jackd alsa_pcm backend driver?
To speak the truth, I've never seen such a setup, either with the (my) new
alsa driver (from jackd 0.99.42) nor with karten's original one. But
that's probable, due to the fact that I own a US-224, and I'm happy with 2
channels which, I repeat, its what I ever seen.
BTW, shouldn't the US-428 have 8 playback channels, the US-224 have 4, and
finally 2 for US-122?
Karsten, would you kindly checkon whether this makes sense? Is there
anything (that I) left behind? Things to check are about:
- using standard "alsa" driver code-path against "hw:N"
- using (my) experimental "alsa" driver against "hw:N,2" (rawusb)
- using yours original patch for the "usx2y" driver against "hw:N"
and see if whether there is any difference regarding the number of
channels for the US-428. IMO the correct number of channels should be
present on ALL of the above.
Feel free to point out if I did any mistake ;)
Cheers.

Hey all,
So my US428 seems to be behaving now(although with the Layla20
that I just bought, the tascam is being used more as a control
surface then an audio interface). But I can't get any audio input
on channels 3 and 4. Jack seems unable to start the tascam as a 4
channel device. Is there something I have to do to enable those
channels? Thanks
hmmmm, have you tried rui's addition to jack's alsa driver?
if so, it could be that one doesn't yet support channel 3+4.
don't know exactly, haven't checked yet.
currently you can use ch 3 and 4 with my usx2y jack driver.
best regards,
Karsten
