use hda-analyzer to check whether node 0x10 mono pin complex is the subwoofer or not
1) set pin-ctls of node 0x10 to OUT 2) check the power setting of node 0x10, 0x1a, 0x19 are D0 3) either connect node 0x19 to node 0x13 or node 0x1c 4) if you connect node 0x19 to 0x1c a) unmute amp-out and change the volume slider of node 0x1c b) unmute the amp-in of either node 0x13 or node 0x14 in node 0x1b and keep the other amp-in mute c) ensure the power setting of above nodes are D0 Node 0x1b [Audio Mixer] wcaps 0x20050b: Stereo Amp-In Amp-In caps: ofs=0x17, nsteps=0x1f, stepsize=0x05, mute=1 Amp-In vals: [0x97 0x97] [0x97 0x97] [0x97 0x97] [0x97 0x97] [0x97 0x97] [0x97 0x97] Power: setting=D0, actual=D0 Connection: 6 0x13 0x14 0x0a 0x0c 0x0e 0x0f -- Node 0x0d [Pin Complex] wcaps 0x400501: Stereo Control: name="Speaker Phantom Jack", index=0, device=0 Pincap 0x00010050: OUT EAPD Balanced EAPD 0x2: EAPD Pin Default 0x92170110: [Fixed] Speaker at Int Front Conn = Analog, Color = Unknown DefAssociation = 0x1, Sequence = 0x0 Misc = NO_PRESENCE Pin-ctls: 0x40: OUT Power: setting=D0, actual=D0 Connection: 3 0x13* 0x14 0x1c Node 0x10 [Pin Complex] wcaps 0x400500: Mono Pincap 0x00000010: OUT Pin Default 0x40f000f0: [N/A] Other at Ext N/A Conn = Unknown, Color = Unknown DefAssociation = 0xf, Sequence = 0x0 Pin-ctls: 0x00: Power: setting=D0, actual=D0 Connection: 1 0x1a Node 0x13 [Audio Output] wcaps 0xd0c05: Stereo Amp-Out R/L Control: name="Speaker Playback Volume", index=0, device=0 ControlAmp: chs=3, dir=Out, idx=0, ofs=63 Control: name="Speaker Playback Switch", index=0, device=0 ControlAmp: chs=3, dir=Out, idx=0, ofs=0 Device: name="STAC92xx Analog", type="Audio", device=0 Amp-Out caps: N/A Amp-Out vals: [0x78 0x78] Converter: stream=8, channel=0 Power: setting=D0, actual=D0 Delay: 13 samples Node 0x14 [Audio Output] wcaps 0xd0c05: Stereo Amp-Out R/L Control: name="Headphone Playback Volume", index=0, device=0 ControlAmp: chs=3, dir=Out, idx=0, ofs=63 Control: name="Headphone Playback Switch", index=0, device=0 ControlAmp Node 0x19 [Audio Selector] wcaps 0x300501: Stereo Power: setting=D0, actual=D0 Connection: 3 0x13* 0x14 0x1c Node 0x1a [Audio Mixer] wcaps 0x200500: Mono Power: setting=D0, actual=D0 Connection: 1 0x19 Node 0x1b [Audio Mixer] wcaps 0x20050b: Stereo Amp-In Amp-In caps: ofs=0x17, nsteps=0x1f, stepsize=0x05, mute=1 Amp-In vals: [0x97 0x97] [0x97 0x97] [0x97 0x97] [0x97 0x97] [0x97 0x97] [0x97 0x97] Power: setting=D0, actual=D0 Connection: 6 0x13 0x14 0x0a 0x0c 0x0e 0x0f Node 0x1c [Audio Selector] wcaps 0x30050d: Stereo Amp-Out Amp-Out caps: ofs=0x1f, nsteps=0x1f, stepsize=0x05, mute=1 Amp-Out vals: [0x9f 0x9f] Power: setting=D0, actual=D0 Connection: 1 0x1b -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1093792 Title: [HP ENVY 4 Notebook PC, IDT 92HD91BXX, Speaker, Internal] Playback problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1093792/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
