Public bug reported: The pcm_multi plugin is used to join two or more soundcards together to create one virtual card. THis is very useful for something like the jack audio connection kit. However, it doesn't work when an attempt is made to use it in full duplex mode.
The attached patch works around this issue. ** Affects: alsa-lib (Ubuntu) Importance: Undecided Status: Unconfirmed -- The pcm_multi plugin does not currently allow full duplex use of two or more soundcards simultaneously. https://launchpad.net/bugs/66657 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
