Thank you John, I did some more testing.
Apparently the pattern I get in REW at 96 kHz s the same I get with arecord whenever I try to capture 4ch at samplerates >= 96 kHz. So it seems the Linux driver does not support properly the 4 x 24/96 capture, but does not "forbid" it to applications...
I have some more details, not sure if useful though.
What happens is that channel mapping and functionality gets screwed up:
- ch. 1 reads a sinc function with a 2 kHz repetition (!)
- ch. 2, 3 are now R, L but with high noise floor and high gain (guess the former is consequence of the latter)...
Thank you John, no worries. I understand the amount of factors at play and this is likely impossible to reproduce without the same interface and OS.
But let me clarify a bit: alsamixer has a slider for the samplerate of the soundcard from which I can see the response of the hardware is...
Hi all,
first of all let me express my appreciation for the degree of maturity this application has reached.
Then, I come to my problem.
I have recently become in possession of a glorious E-MU 0404 USB, but I am experiencing odd behaviour under Linux:
- card works as expected up to 48 kHz
- at...
