Dear alsa-users! I have a mainboard (Commell LV-67K, QM77) which has a Realtek-ALC888 HDA-sound-chip on board. On the rear side of the board there are only 3 jacks: Line-in (blue), line-out (green), Mic-in (pink). On-board is also a socket for speakers and another Mic-in. So far - so well known. Now I am trying to reconfigure / retask at least line-in as an additional line-out for the surround channels, and ideally the mic-in as a third line-out for the side-channels. I have read in the ALC888 datasheet: "All analog IO are input and output capable (...). All analog IOs can be re-tasked according to user's definitions, or automatically switched depending on the connected device type." Also here at http://manpages.ubuntu.com/manpages/lucid/man4/snd_hda.4freebsd.html I see hints that I should be somehow possible in theory. I have googled and tried a lot for several days now to get it working, but didn't succeed. I tried different model-parameters for the snd-hda-intel driver, for example 3jack-dig, 3stack-6ch-dig, 3stack-digout, 6stack-dig and even test (I compiled the kernel with CONFIG_SND_DEBUG, CONFIG_SND_DEBUG_VERBOSE, SND_HDA_HWDEP, SND_HDA_RECONFIG ). I also tried probe_mask=0x10f, without really knowing what it does... ;-) A strange thing for me is, that the available controls in alsamixer _never_ changed, whatever model I tried, not even with "test"! Especially the "Channel Mode"-Switch (to select between 4ch, 6ch, 8ch) is missing in the mixer. I am using a quite up-to-date gentoo installation (baselayout2) with kernel-3.7.1 and of course kernel alsa-drivers. I set the model in /etc/modprobe.d/alsa.conf and see that it gets used for example in /sys/class/sound/hwC0D3/modelname. Here are the hda-related boot-messages I get: ------------------------------------------------------------------------ Dec 18 11:33:02 testbox kernel: snd_hda_intel 0000:00:1b.0: irq 45 for MSI/MSI-X Dec 18 11:33:02 testbox kernel: hda-intel: chipset global capabilities = 0x4401 Dec 18 11:33:02 testbox kernel: hda-intel: Clearing TCSEL Dec 18 11:33:02 testbox kernel: hda-intel: SCH snoop: Enabled Dec 18 11:33:02 testbox kernel: hda-intel: codec_mask = 0x8 Dec 18 11:33:02 testbox kernel: hda-intel: codec #3 probed OK Dec 18 11:33:02 testbox kernel: hda_codec: ALC888: SKU not ready 0x00000100 Dec 18 11:33:02 testbox kernel: autoconfig: line_outs=4 (0x14/0x16/0x15/0x17/0x0) type:line Dec 18 11:33:02 testbox kernel: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) Dec 18 11:33:02 testbox kernel: hp_outs=1 (0x1b/0x0/0x0/0x0/0x0) Dec 18 11:33:02 testbox kernel: mono: mono_out=0x0 Dec 18 11:33:02 testbox kernel: dig-out=0x1e/0x0 Dec 18 11:33:02 testbox kernel: inputs: Dec 18 11:33:02 testbox kernel: Rear Mic=0x18 Dec 18 11:33:02 testbox kernel: Front Mic=0x19 Dec 18 11:33:02 testbox kernel: Line=0x1a Dec 18 11:33:02 testbox kernel: CD=0x1c Dec 18 11:33:02 testbox kernel: dig-in=0x1f Dec 18 11:33:02 testbox kernel: ==> lo_type=0, wired=1, mio=1, badness=0x0 Dec 18 11:33:02 testbox kernel: multi_outs = 14/16/15/15 : 2/3/4/5 Dec 18 11:33:02 testbox kernel: hp_outs = 1b/0/0/0 : 25/0/0/0 Dec 18 11:33:02 testbox kernel: spk_outs = 0/0/0/0 : 0/0/0/0 Dec 18 11:33:02 testbox kernel: ==> Best config: lo_type=0, wired=1, mio=1 Dec 18 11:33:02 testbox kernel: multi_outs = 14/16/15/15 : 2/3/4/5 Dec 18 11:33:02 testbox kernel: hp_outs = 1b/0/0/0 : 25/0/0/0 Dec 18 11:33:02 testbox kernel: spk_outs = 0/0/0/0 : 0/0/0/0 ********* This might be of interest: *********** Dec 18 11:33:02 testbox kernel: realtek: No valid SSID, checking pincfg 0x00000100 for NID 0x1d Dec 18 11:33:02 testbox kernel: realtek: Enable default setup for auto mode as fallback Dec 18 11:33:02 testbox kernel: realtek: Enable HP auto-muting on NID 0x1b Dec 18 11:33:02 testbox kernel: input: HDA Intel PCH Line as /devices/pci0000:00/0000:00:1b.0/sound/card0/input4 Dec 18 11:33:02 testbox kernel: input: HDA Intel PCH Front Mic as /devices/pci0000:00/0000:00:1b.0/sound/card0/input5 Dec 18 11:33:02 testbox kernel: input: HDA Intel PCH Rear Mic as /devices/pci0000:00/0000:00:1b.0/sound/card0/input6 Dec 18 11:33:02 testbox kernel: input: HDA Intel PCH Front Headphone as /devices/pci0000:00/0000:00:1b.0/sound/card0/input7 Dec 18 11:33:02 testbox kernel: input: HDA Intel PCH Line Out Side as /devices/pci0000:00/0000:00:1b.0/sound/card0/input8 Dec 18 11:33:02 testbox kernel: input: HDA Intel PCH Line Out CLFE as /devices/pci0000:00/0000:00:1b.0/sound/card0/input9 Dec 18 11:33:02 testbox kernel: input: HDA Intel PCH Line Out Surround as /devices/pci0000:00/0000:00:1b.0/sound/card0/input10 Dec 18 11:33:02 testbox kernel: input: HDA Intel PCH Line Out Front as /devices/pci0000:00/0000:00:1b.0/sound/card0/input11 Dec 18 11:33:02 testbox kernel: hda_intel: Disabling MSI Dec 18 11:33:02 testbox kernel: ACPI Warning: 0x0000efa0-0x0000efbf SystemIO conflicts with Region \_SB_.PCI0.SBUS.SMBI 1 (20120913/utaddress-251) Dec 18 11:33:02 testbox kernel: ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver Dec 18 11:33:02 testbox kernel: hda-intel: chipset global capabilities = 0x2403 Dec 18 11:33:02 testbox kernel: hda-intel: Clearing TCSEL Dec 18 11:33:02 testbox kernel: hda-intel: Setting Nvidia snoop: 1 Dec 18 11:33:02 testbox kernel: hda-intel: codec_mask = 0xf Dec 18 11:33:02 testbox kernel: hda-intel: Enable delay in RIRB handling Dec 18 11:33:02 testbox kernel: hda-intel: codec #0 probed OK Dec 18 11:33:02 testbox kernel: hda-intel: codec #1 probed OK Dec 18 11:33:02 testbox kernel: hda-intel: codec #2 probed OK Dec 18 11:33:02 testbox kernel: hda-intel: codec #3 probed OK -------------------------------------------------------------------------- The complete alsa-info.txt generated by alsa-info is here: http://pastebin.com/3Hdyzfni Currently I am stuck and would be very thankful if someone could point me in the right direction :-) Bernhard ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
