I've gone through the nodes, now making sure to test each channel separately, but still nothing. Anything else we could try? I'm pretty sure the microphone is not in the Realtec ALC255 protocol, but still connected to the Intel sound card.

The computer has been released a couple of months ago and it's Intel Skylake -based with a Sunrise Point -based motherboard. INFO: The problem exists in Ubuntu 15.10 too, only microphone jack detected. Currently using Ubuntu 16.04 for proper hardware support. Alsa reports the audio device to be: Card: HDA Intel PCH Chip: Intel Skylake HDMI The speakers are working fine, but both alsamixer and pavucontrol (Pulseaudio Volume Control) raport the unplugged external microphone connector as the only sound input. I have tried many of the alsa model configurations (options snd-hda- intel model=something) without success, alsa finds only the microphone jack, which works fine when I plug an external microphone in it. Here's some info: lspci | grep -I audio: 00:1f.3 Multimedia audio controller: Intel Corporation Sunrise Point-H HD Audio (rev 31) cat /proc/asound/cards: 0 [PCH ]: HDA-Intel - HDA Intel PCH HDA Intel PCH at 0x84320000 irq 128 And a clip from dmesg | grep snd: [ 3.019164] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) [ 3.047505] snd_hda_codec_realtek hdaudioC0D0: autoconfig for ALC255: line_outs=1 (0x14/0x0/0x0/0x0/0x0) type:speaker [ 3.047508] snd_hda_codec_realtek hdaudioC0D0: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) [ 3.047510] snd_hda_codec_realtek hdaudioC0D0: hp_outs=1 (0x21/0x0/0x0/0x0/0x0) [ 3.047511] snd_hda_codec_realtek hdaudioC0D0: mono: mono_out=0x0 [ 3.047512] snd_hda_codec_realtek hdaudioC0D0: dig-out=0x1e/0x0 [ 3.047512] snd_hda_codec_realtek hdaudioC0D0: inputs: [ 3.047514] snd_hda_codec_realtek hdaudioC0D0: Mic=0x1a One problem is that I can't find any model options (options snd-hda- intel model=something) or other parameters for the card's model (ALC255), I suppose this issue is relatively new. /Dennis --- ApportVersion: 2.19.2-0ubuntu6 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: dennis 1180 F.... pulseaudio CurrentDesktop: GNOME DistroRelease: Ubuntu 16.04 InstallationDate: Installed on 2015-11-11 (23 days ago) InstallationMedia: Ubuntu-GNOME 16.04 LTS "Xenial Xerus" - Alpha amd64 (20151110) Package: alsa-driver (not installed) ProcVersionSignature: Ubuntu 4.2.0-19.23-generic 4.2.6 Tags: xenial Uname: Linux 4.2.0-19-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm bumblebee cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 09/25/2015 dmi.bios.vendor: Insyde Corp. dmi.bios.version: V1.02 dmi.board.asset.tag: No Asset Tag dmi.board.name: Aspire VN7-792G dmi.board.vendor: Acer dmi.board.version: V1.02 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: Acer dmi.chassis.version: V1.02 dmi.modalias: dmi:bvnInsydeCorp.:bvrV1.02:bd09/25/2015:svnAcer:pnAspireVN7-792G:pvrV1.02:rvnAcer:rnAspireVN7-792G:rvrV1.02:cvnAcer:ct10:cvrV1.02: dmi.product.name: Aspire VN7-792G dmi.product.version: V1.02 dmi.sys.vendor: Acer To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1523100/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
