That's wrong, it appears all outputs and inputs are to be multiplexed through one device. Okay, let's try to get the front speakers output working. 1) Ensure that the kernel is compiled with CONFIG_SND_HDA_HWDEP and CONFIG_SND_HDA_RECONFIG enabled. 2) Download the hda-verb tool from <http://ftp.suse.com/pub/people/tiwai/misc/> and compile it. The nodes are connected and labelled like this: 0x02 -> 0x0c green (rear) 0x03 -> 0x0d orange 0x04 -> 0x0e black 0x05 -> 0x0f grey 0x06 -> 0x10 green (front) 0x08 <- 0x12 pink 0x09 <- 0x13 internal (aux?) 0x0a -> 0x14 RCA 0x0b <- 0x15 blue On the left are nodes connecting to the PC's bus, on the rights are jacks. The nodes currently used by the driver for output/input are 0x02 and 0x08. To configure the rear green jack for line output, run: hda-verb /dev/snd/hwdepC1D0 0x0c set_pin_widget_control 0x40 To configure the rear green jack for HP output, run: hda-verb /dev/snd/hwdepC1D0 0x0c set_pin_widget_control 0xc0 To configure the front green jack for line output, run: hda-verb /dev/snd/hwdepC1D0 0x10 set_pin_widget_control 0x40 To configure the front green jack for HP output, run: hda-verb /dev/snd/hwdepC1D0 0x10 set_pin_widget_control 0xc0 To output what plays to the speakers also to HP and/or digital: 1) start playing something 2) find out the stream/channel IDs: hda-verb /dev/snd/hwdepC1D0 0x02 get_conv 0 3) configure other outputs for these stream/channel IDs: hda-verb /dev/snd/hwdepC1D0 0x06 set_channel_streamid 0x?? hda-verb /dev/snd/hwdepC1D0 0x0a set_channel_streamid 0x?? (where ?? is the value returned in step 2) BTW: Does multichannel output work? (try speaker-test) In theory, the side/surround channels should not need any configuration.
