[LAU] Jack-hardware bridging issue

[Iain Mott]

Hi list,

I am running a telephony daemon on a laptop that gives no audio 
interface configuration options and I wish to use it with Jack. I'm 
confused as to whether or not it is using ALSA. If Jack is already 
running (with pulseaudio-module-jack uninstalled) and configured to use 
an external USB sound card, starting the daemon results in its audio i/o 
being connected with the laptop's internal mic and speaker. If Jack is 
not running, the daemon connects with card 1 listed by "aplay -l", which 
happens to be the USB card. However, if Jack is running with 
pulseaudio-module-jack installed and all other non-jack audio apps are 
routed via the sink to the USB card, the telephony daemon again connects 
and runs correctly with laptop's internal hardware.

I don't think ALSA-Jack loopback scripts will work as I think 
pulseaudio-module-jack does this job now.  Is there a solution with 
kernel modules? Can someone please put me in the right direction?

Thanks!

Iain
