I managed to get it working by disabling all my analogue ports in ASIO config, so I only keep 2 SPDIF ports on position 1 and 2. Now I can stop music and start again.This appears to be an ASIO4ALL issue. After stopping the used ASIO channels are no longer available.
I have a somewhat similar issue with ASIO4ALL on my develop machine from time to time (onboard Sigmatel device). In my case it results in playing silence because the positions of the missing channels are taken by others. I your case it results in an error because there are no channels left at all at position 7 and 8...
I don't have a solution for this now. Maybe other ASIO4ALL users have experience with this issue?
Wow.. what a good sound! Thanx for the plugin!
