Description Matt 2006-04-18 10:11:24 UTC

These two patches, one for alsa-lib and one for jack-audio-connection-kit, will enable jack to handle two delta1010lt soundcards simultaneously. Using a custom .asound file enabling all inputs from both soundcards without the pacthes jack will error: mmap-based access is not possible for the capture stream of this audio interface. Without the alsa-lib patch jack will start but no jack apps will work normally eg no transport. More info on this topic is at this site: http://www.sound-man.co.uk/linuxaudio/ice1712multi.html. There is also a patch for amd64 users to get rid of the floating point exception error.

alsa-lib patch: http://www.sound-man.co.uk/linuxaudio/pcm_multi-patch
jack-audio-connection-kit patch: http://www.sound-man.co.uk/linuxaudio/mmap_complex-patch-0.100.7

Also for jack is the amd64 patch: http://www.sound-man.co.uk/linuxaudio/fpexception-patch-0.100.7

Note: I havent tested the amd64 patch yet so I'm unsure if it works or not.

update: the mmap_complex is present in the portage versions and the current upstream svn repository.

I suggest waiting for upstream on this one.
do you know if the patch for alsa-lib will be merged upstream?

reopen if there's action needed.
