I guess it's another firmware...
The board has no firmware to load.
well, I was thinking of the eeprom.
First you should check whether the exactly same codec chip, AK4524, on it.
Yes, it has, but another model no (or whatever it is). I just have both cards - the original Phase 22 and the new TS22 here:
Phase 22: AKM AK4524VF 193A0547N VIA ENVY24HT-S VT1721-0522CD 2IA0000551
TS22: AKM AK4524VF 247A0805N VIA ENVY24HT-S VT1721-0810CD 2IA0001861
The PCBs are nearly the same, but the TS22 lacks the following parts: X3 quartz UD09 and UD10 (both ICs)
On the Back of the Swissonic TS22 it says "Terrasoniq" - which is knows as yet another vendor of sound cards. Swissonic seems to be just another brand of the same product.
Something about the noise / recording: When I unpug the lines, the noise still persists. When I fade down both ADC lines with alsamixer, the noise perists until I reach 0. Then it is mute. When I fade up ADC1 I can hear some of the to-be-recorded signal very distorted behind the noise.
