Post subject:  USB soundcard delay problem

Hello!

I have a problem with delay/latency.

I’m using the Carambola 2 and a USB soundcard.

I have a program reading from /dev/dsp and then writing to /dev/dsp directly after.

The problem is that the delay is high! About 0,5s or something.

Also tried to read from /dev/dsp send it to a computer (with built in soundcard) over Ethernet and play, again with a high delay (like 0,5s).

Is there any big delay in USB drivers for audio input? And if so can it be minimized in some way?
