My design has only a 24Mhz oscillator for the CLK pin, and a 45/49Mhz oscillator for PORT_MCLK_IN.

Code: Select all

MCLK_441 (1024*44100)
MCLK_48  (1024*48000)

i'm missing something obvious?
*** with v6.15 it works fine.
Is the xu208 still supported in the current version? I saw some open threads with issues with it.

[Ross]

208 will operate just fine

My initial guess would be the device is not properly receiving an mclk, and thus the sample rate change request cannot complete.

Check the mclk input is connected to the correct port/pin.

Failing that post the result of xrun --dumpstate <your_binary>.xe when its in the failing state and that should give us some clues as to the issue.

Thanks for the reply.
Problem solved. I love XMOS.

Let me ask the expert one more question.

The Microsoft page says that Thesycon develops the Windows native UAC2 PnP drivers.
Is Thesycon also on Linux?
What currently delivers better quality/performance in terms of PnP drivers? Linux ALSA or Windows WASAPI?

best regards.

Yes, usbaudio2.sys was authored by Thesycon, the original author of usbaudio.sys had left Microsoft some time ago. MS approached us and we pointed them straight to Thesycon.

I think it depends on what you mean by "quality/performance". Most people bean "bit perfect audio" in this case, I suppose - both are capable of providing this.
