Hello folks, I have an OrangePi Zero 2*W *actually running with Armbian 6.7.4 Kernel. When I setup g_audio module I can´t achieve settings higher than 84578 hz samplerate with S24_3LE (3Byte) and no more than 127360 Hz with S16. Both is nearly or exactly 512 Byte packet size tho. Tuning and optimising packet sizes and intervalls did not helped. I think it is an issue with the USB implementation in the device tree. Althought 2W is a H618 in the dtb/dts is still H616 modules used (I decompilied dtb) and I already using Zero 3 (H618) device tree.
Errors when setup g_audio comes from UDC musb-hdrc.4.auto and it states "couldn´t find an available UDC" or "[ 7020.314150] g_audio gadget.0: FS Capture: Req. wMaxPacketSize 1158 at bInterval 1 > max ISOC 1023, may drop data!" Maybe someone can help! *Maybe @Andre Przywara can help!* BR Ricardo -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
