I checkveed dmesg, this message appears after each aplay's
unsuccesful attempt:
cannot submit datapipe for urb 0, err = -38
What is this "urb 0"?
I found this in the LAU archive from , pertaining
to this error message:
"> > > ALSA: could not start playback (Broken pipe)
kernel: cannot submit datapipe for urb 0, err = -28
28 = ENOSPC: "This request would overcommit the usb bandwidth reserved
for periodic transfers (interrupt, isochronous)."
This doesn't seem to be quite correct for two 16-bit stereo streams.
Which kernel and host controller driver are you using?
Probably you should just deactivate bandwith checking in the kernel
config. "
This happened after Clemens advised Chris Eckert to try loading
the snd-usb-audio with "nrpacks=1" and setting the period in jack
to 3. But, I didn;t pass this argument with the snd-usb-audio
and didn't set jack to use 3 periods. Would deactivating
bandwidht checking work for me too, then?
Hiram.
