# .asoundrc for two Delta 1010s

# Create virtual devices out of multiple soundcards.
# ICE1712 chip has 12 capture channels and 10 playback channels.
# No. of channels in slaves must equal 12 for capture and 10 for playback
# otherwise "invalid argument" errors result.
# If you're using JACK without MMAP_COMPLEX support (are you sure you want to do this?)
# you need the ttable devices shown below.
# To start jackd with ttable devices, use this command:
# jackd -d alsa -C ttable_cap -P ttable_play
# with additional options as required.
# This will really screw up low latency operation, so it's much better
# to use JACK with the MMAP_COMPLEX patch.
