Unable to play and record simultaneously. when 8ch file is playing, recording is showing the following error:

It seems an issue on a driver level which prevent processing of more than 8 channels. P.S: Anyway, could you suggest an easy way to passthrough s/pdif digital stereo to analog stereo? (5.1 upmix?) tried "arecord -D plughw:3 | aplay -D plughw:3" but this gives underrun\overrun errors -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/748937 Title: Lack of "Analog Surround 7.1 Output + (Digital|Analog) Stereo Input" sound profile for cm6206 (cm106 like) USB sound card. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
