First of all I'll prefer communicate via Linux-usb mailing list
<linux-usb@vger.kernel.org>. Let's keep this mailing list address in CC.
And one more thing, keep on the beginning of subject follow string:
"usb: dwc2: "
Thank you for your email. I'll dedicate time on the next week to debug
your case.
Thanks,
Minas

Could you please send regdump and debug log for failing case.

Thanks a lot for your reply.
Attaching regdump-960bytes.txt for 32kHz/16b/15ch both playback and
capture, bInterval=4 in
https://github.com/torvalds/linux/blob/master/drivers/usb/gadget/function/f_uac2.c#L287
=> 960 bytes packet size every 1ms. This mode does not work for EP OUT
(host playback -> gadget -> RPi capture)
Also attaching regdmp-896bytes.txt for 32kHz/16b/14ch which works OK,
bitperfect transmission.
For debug - I enabled this:
file gadget.c +p;file u_audio.c +p; file f_uac2.h +p
debug-960bytes.txt - not working:
Every 8 packets:
[ 2037.700760] dwc2 fe980000.usb: dwc2_hsotg_epint: ep1(out)
DxEPINT=0x00000002

[ 2037.700780] u_audio_iso_complete: iso_complete status(-61) 0/960
debug-896bytes.txt - working OK:
EPDisbld is not every 8 packets, sometimes I see:

I do not know if the debug info was sufficient. Please should I provide
more?
Thanks a lot.
Best regards,

Sorry for delay. I haven't enough time to investigate deeper.
This type of issue depend on timings: packet sizes and board DMA
performance.
Anyway, could you please elaborate:
1. 960 bytes case. Is it high bandwidth transfer? I mean how many
packets sending in 1 (u)frame?
2. Could you please print hsotg->frame_number in function
dwc2_gadget_handle_out_token_ep_disabled().
3. No any chance to record USB trace?
Thanks,
Minas

Could you please perform follow 3 tests:
1. Test#1. Disable all debug prints for dwc2 driver and test again 960
bytes mps.
2. Test#2. If not help above then re-enable debug prints and apply below
patch, test again and provide me full dmesg.

Do you mean without any patches, with the existing code? That will
result in the existing (incorrect) behaviour.
I will do all the other tests, thanks alot for your effort.

Pavel.

Yes, without any patch, just disable debug prints which will improve
timings.
