> ac3jack is a tool for creating an AC3 (Dolby Digital) multichannel
> stream from its JACK input ports.  Using this tool, an AC3 stream (up
> to 5.1 channels) is encoded in realtime and either written to a file
or
> streamed to standard output.
> 
> When streamed to stdout and piped through the ALSA tool 'ac3dec -C',
> the AC3 stream can be passed out the SPDIF port on your audio
interface
> for connection to a multichannel surround receiver.  In this way,
> you can achieve full 5.1 surround mixing and monitoring of your JACK
> applications with a single digital cable, and no need for hardware
> supporting discrete inputs and outputs.
> 
> AC3 is a compressed audio stream, so quality is somewhat compromised.
> It is the price you pay for easy surround sound.  After all, if it is
> good enough for DVD and film soundtracks, it must be OK.

> Please try it out, read the usage notes, and let me know of any
