Adjust the badness tables for VIA so that 7.1 outputs are activated for the cost of missing independent HP. Once when we implement the dynamic DAC switching to multiple outputs, this conflicts will be eased in future... This mean some feature are lost https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/pci/hda/patch_via.c?id=2525050518496dfd6905abfa8d6d34288eed36d7 If you have selected ac97 front audio panel instead of hda front audio panel in BIOS setup, both front hp and front mic disable jack detection Misc = NO_PRESENCE You have to provide pulseaudio verbose log since there is only headphone phantom jack and no headphone playback volume and http://fedoraproject.org/wiki/How_to_debug_PulseAudio_problems Node 0x1d [Pin Complex] wcaps 0x40058d: Stereo Amp-Out Control: name="Headphone Playback Switch", index=0, device=0 ControlAmp: chs=3, dir=Out, idx=0, ofs=0 Control: name="Front Headphone Phantom Jack", index=0, device=0 Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-Out vals: [0x00 0x00] Pincap 0x0000233c: IN OUT HP Detect Vref caps: HIZ 50 100 Pin Default 0x0221411f: [Jack] HP Out at Ext Front Conn = 1/8, Color = Green DefAssociation = 0x1, Sequence = 0xf Misc = NO_PRESENCE Pin-ctls: 0xc0: OUT HP VREF_HIZ Unsolicited: tag=00, enabled=0 Power states: D0 D1 D2 D3 Power: setting=D0, actual=D0 Connection: 2 0x16* 0x25 Node 0x1e [Pin Complex] wcaps 0x40058d: Stereo Amp-Out Control: name="Front Mic Boost Volume", index=0, device=0 ControlAmp: chs=3, dir=In, idx=0, ofs=0 Control: name="Front Mic Phantom Jack", index=0, device=0 Amp-Out caps: ofs=0x00, nsteps=0x00, stepsize=0x00, mute=1 Amp-Out vals: [0x80 0x80] Pincap 0x0000233c: IN OUT HP Detect Vref caps: HIZ 50 100 Pin Default 0x02a19138: [Jack] Mic at Ext Front Conn = 1/8, Color = Pink DefAssociation = 0x3, Sequence = 0x8 Misc = NO_PRESENCE Pin-ctls: 0x21: IN VREF_50 Unsolicited: tag=00, enabled=0 Power states: D0 D1 D2 D3 Power: setting=D0, actual=D0 Connection: 2 0x16* 0x25 http://cgit.freedesktop.org/pulseaudio/pulseaudio/tree/src/modules/alsa/mixer/paths/analog-output-headphones.conf >> > >> > First some details: >> > I have an VT1708S sound card with a rear panel and and top/front panel My Speakers are plugged on the rear panel corresponding to the "surround" channel on alsamixer.
