The current alsa rate feedback rate feedback format is 12.13 in 4 bytes. Clemens has a patch to make the rate feedback format automatic such that it will work with 10.14 16.16 or any other formats. We are still testing the patch put . Currently with 12.13 format rate feedback works well.
How does it come that alsa uses 12.13? I don't see that mentioned in the specs? Is it right or left aligned in the 4 bytes?
For example, AT91SAM7 has a limitation of EP siE of 64 bytes for EP 3 used for ISO transfers. There may also be a limitation in that the Same EP number cannot be used for both IN and OUT.
Hm, I'm not sure about this. You think I should move the feedback pipe into it's own EP? I will recheck the At91SAM7 specs later, to see if I can find a note on such a limitation.
Thanks, Julian
