Description: USB subwoofer designed for the original slot-loading imacs. Works alone out of the box, or with an existing sound card (for treble output) when used with an .asoundrc file such as:
Code:
pcm.multi { type multi; slaves.b.pcm "hw:0,0"; slaves.b.channels 2; slaves.c.pcm "hw:1,0"; slaves.c.channels 2; bindings.0.slave b; bindings.0.channel 0; bindings.1.slave b; bindings.1.channel 1; bindings.2.slave c; bindings.2.channel 0; bindings.3.slave c; bindings.3.channel 1; } pcm.!dmix { type plug slave { pcm multi channels 4 } } pcm.!default { type plug slave.pcm "dmix" slave.channels 4 route_policy duplicate }
Note that this config has no provisions for crossovers or syncing (noticable after 20 minutes of constant play with my IBM TP600e). This also assumes that your main card and isub are identified as hw0,0 and hw1,0 by alsa. Original taken from http://gentoo-wiki.com/HOWTO_Surround_Sound
Modified for two cards instead of three. If you have any suggestions for config improvements please message me.
