Hi Rui,
please try to enable audio out with "us428control -v2 -D hw:1" like this:
- toggle INPUT MONITOR until us428control says "...Light is 1"
- then move Fader3 to max and play some audio.
This is just a guess assuming audio out is mapped on us224 internal mixer 2,
input monitor channel 1 is mapped on us224 internal mixer 0 and input
monitor channel 2 is mapped on us224 internal mixer 1.
- Please also try your guitar on both inputs: move faders 1 & 2 to see if
sound is routed to the outputs.
We have to tweak us428control to add real us224 support.
Above is just to verify that the current us428 internal mixer mechanics is
usable for the us224.
Concerning us224's Lights I'm currently left in the dark....
For us428 I found that a 7Byte long USB-Message on pipe 4 is a Lights set
command, while a 5Byte long is an internal mixer set command.
You could tweak us428control to toggle the 0'th light instead of the 25'th
light, which is InputMonitor Light on us428. the 0th light is Select Channel
1 on the us428.
Exchange Cus428State.cc Line 118 , 119
Light[0].Value = StateInputMonitor() ?
SelectInputMonitor : Select;
Light[2].Value = StateInputMonitor() ?
MuteInputMonitor : Mute;
for
Light[0].Value = 0x55;
Light[2].Value = 0xAA;
to check light mechanics.
If there's still no lights, some usb snooping on windoz might help.
I've some specially tuned stuff here which I could send you then.
cheers,
Karsten
