Hi list, this is an exerpt from 8.1R detailed Release Notes: 2.2.2.1 Multimedia Support [snipped] The snd_hda(4) driver now supports multichannel (4.0 and 7.1) playback support. The 5.1 mode support is disabled now due to unidentified synchronization problem. Devices which supports the 7.1 mode can handle the 5.1 operation via software upmix done by sound(4). Note that stereo stream is no longer duplicated to all ports. I'm interesting in what way can I restore the old behaviour, when stereo stream is duplicated to the black and grey sound card output connectors? Thanks, Serguey.
