I have had some luck with getting 4 channels to register using the multi plugin.
I have the following in .asoundrc. ---- pcm.quattro { type multi; slaves.a.pcm "hw:2,0"; slaves.a.channels 3; bindings.0.slave a; bindings.0.channel 0; bindings.1.slave a; bindings.1.channel 1; bindings.2.slave a; bindings.2.channel 2; } ctl.quattro { type hw; card 0; } pcm.q4 { type route; slave.pcm "quattro"; ttable.1.1 1; ttable.2.2 1; } ---- When I run jackd I get this output though: ---- jackd -v -d alsa -d q4 jackd 0.37.1 Copyright 2001-2002 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details 611 waiting for signals creating alsa driver ... q4|1024|2|48000|swmon new client: alsa_pcm, id = 1 type 1 @ 0x8067930 fd = 14 port alsa_pcm:in_1 buf shm key 0x164398c5 at offset 4096 bi = 0x8066d00 registered port alsa_pcm:in_1, offset = 4096 port alsa_pcm:in_2 buf shm key 0x164398c5 at offset 8192 bi = 0x8066d10 registered port alsa_pcm:in_2, offset = 8192 port alsa_pcm:in_3 buf shm key 0x164398c5 at offset 12288 bi = 0x8066d20 registered port alsa_pcm:in_3, offset = 12288 port alsa_pcm:in_4 buf shm key 0x164398c5 at offset 16384 bi = 0x8066d30 registered port alsa_pcm:in_4, offset = 16384 registered port alsa_pcm:out_1, offset = 0 registered port alsa_pcm:out_2, offset = 0 registered port alsa_pcm:out_3, offset = 0 registered port alsa_pcm:out_4, offset = 0 -- jack_rechain_graph(): client alsa_pcm: inprocess client, execution_order=0.
