Hi,
I have 2 CM6571 usb sound cards.
In Ubuntu, i want to use these 2 cardds simultaneously. I open 2 terminals,
and arecord -D plughw:1,0 | aplay -D plughw:1,0 in one terminal, it works

another terminal, in second terminal, it

I don't know. Perhaps by making both cards one virtual card and using
S/PDIF for sync or by using zita-resampler.

PS: IIRC this year it was discussed at Linux audio user mailing list
[1], if it's possible to sync two USB sound devices. My professional
PCIe card provides a professional sync option, however, IIRC my prosumer
PCI Envy24 cards don't provide a sync option, but AFAIR it's possible to

IIRC the plug'n'play audio USB driver is limited to USB1, for
Cmedia 6571 codecs are intel 8051 based codecs and have firmware on them to
handle the usb protocol, i have another usb codecs which are plantronics,
they have no problem when i use them 8khz and 8 bit, but when i use them as
16 bit and 48khz, the bandwidth problem occurs again.
