Hi Minas, Can you please look at the logs below, when you get a chance? Let me know if you need any more information. Thanks, Palak -----Original Message----- From: Palak SHAH Sent: Monday, February 27, 2023 3:21 PM To: Minas Harutyunyan <Minas.Harutyunyan@xxxxxxxxxxxx>; Maynard CABIENTE <maynard.cabiente@xxxxxxxxxxx> Cc: linux-usb@xxxxxxxxxxxxxxx Subject: RE: usb: gadget: dwc2: not getting audio data Hi Minas, I have attached the following USB traces and debug log. 1) dmesg and usb sniffer logs during driver loading. 2) EP1(OUT) - I play AUDIO on the HOST. And I do arecord on the linux device that acts as USB gadget. So the audio is going OUT from the host. So you will see EP1 OUT. I have attached logs and USB sniffer data, during arecord. I am not testing ISOC EP1(IN) yet. I am still seeing and debugging issues with Ep1(out). 3) When I change UAC1_DEF_REQ_NUM 2 changed to 32, the problem STILL exist with EP1(OUT). ONLY log behaivor is different. In the log I see XferCompl, but I don’t get any data in the arecord. I have attached 2 files. Arecord_command.txt shows what I run. Arecord_output shows what I get after I run the command. 4) I sent you regdump, hw_params, params and fifo in the previous email.

USB trace for arecord (EP1IN ISOC) and debug log. Could you please confirm that after defining UAC1_DEF_REQ_NUM to 32 playing audio (EP1OUT ISOC) no any issue seen?
