This is in the output of dmesg:
[ 8.257450] usb 1-4: parse_audio_format_rates_v2(): unable to find clock source (clock -19)
Is it related? Is it possible to discuss this on the phone with someone at XMOS?

Re: Periodic popping noise on XUF208-128
Thanks again for the reply I should also point out there is a frequency shift, the input sample is 1001Hz, but when frequency analysis is done on the output, it peaks at 1003Hz. I don't believe that is a problem in itself. It is an XUF209-128-TQ64. I can send you the schematic, but I cannot post it ...

Re: Periodic popping noise on XUF208-128
Looks like the image upload didn't work. Is there another way I can send it to you?

Re: Periodic popping noise on XUF208-128
After more testing, I have discovered that popping noise occurs when only one stream is being played, it just takes longer to manifest itself.

Periodic popping noise on XUF208-128
Hi,
I'm working with a board that has a XUF208-128-TQ64 and is connected to a Linux machine by USB. When playing one stream it works well, but when two streams are sent, there is a popping noise with an approximate 2 second interval.
Any suggestions?
Thanks, Jim.
