Hi Giuliano,

Is this yours?

Supposing the TASCAM keeps on being "scheda:2", take a look at

alsamixer -c2

and/or post the output of

amixer -c2

I don't know if this card has an internal mixer that you can access from
alsamixer though, just trying to guess.

Try:

speaker-test -Dfront:USX2Y -c2

You should hear pink noise.

Another thing, have you tried with jack? Try for example:

jackd -dalsa -dhw:USX2Y -n3

(This is in a terminal, as a test. There is a gui frontend called
qjackctl or Jack Control. This command means, more or less: Use the alsa
driver on the card hw:USX2Y in realtime mode, with 3 periods per buffer,
48000 kHz, 1024 frames per period).

If jackd starts, install aqualung (a jack-aware audio player) and try
playing a song.

Many of us use jack to capture / playback audio. Actually, Linux DAWs
depend on jack. Gnome sound preferences is a pulseaudio frontend.  I
don't know if pulseaudio works with your card or not, but you should use
Jack if you want to record music.

Note that both pulseaudio and jack use the alsa driver.

Cheers, Pablo
