Hi,
I have been experimenting with 5.1 USB devices. I'm using them on a Linksys
NSLU2. Some interfaces are reasonable
fast, some are extremely slow due to software sample rate conversion.
Now I'm using a Aureon 5.1 MKII. AFAIK it does hardware samplerate
conversion, but its significantly slower than another "GIGAPort AG"
I have around here.
Can anyone (maybe the driver author) tell me why is this adapter so slow ?
Could it be possible to make it faster tweaking the driver perhaps ?
Why is the maximum buffer so small ? It is just so small, so I'm forced to
add some bigger buffering by my self, creating even more overhead :(
I would have expected that on a USB device the PCM buffer could be arbitrary
large, so why is it so small ?
Thanks you very much for any advice.
Best Regards
Manuel Jander
