There are two playback subdevices and driver is supposed to support 5.1 smartly when the speaker jack is plugged But PA developer seem expect an "2 4 6 channels switch" in all HDA codec **** List of PLAYBACK Hardware Devices **** card 0: NVidia [HDA NVidia], device 0: VT1708S Analog [VT1708S Analog] Subdevices: 2/2 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 http://pulseaudio.org/ticket/743 https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4895 seem bug in alsa driver for rear channels ? _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
