Hello Pratyush,
While at it, could you please do a quick test with designware_udc
at 32, 44.1 and 48KHz sampling rates.
$ insmod g_audio.ko c_srate=32000
$ insmod g_audio.ko c_srate=44100
$ insmod g_audio.ko c_srate=48000
and see if you observe any noise in the captured USB_OUT audio.
Unfortunately I don't have access to anything other than OMAP4.
And I really want to know how UAC2 works with other UDCs.
Thanks much,
-Jassi
