    Default Sound only partially working on Thinkpad Helix

    The helix has four speakers and an headphone jack, two speakers on the tablet itself, two on the detachable keyboard. Running

    Code:
    speaker-test -c2 -l5 -twav
    the keyboard speakers work.

    Running
    Code:
    speaker-test -c4 -l5 -twav
    The tablet speakers also work, but only when the keyboard is attached, and they are recognised as rear left and rear right.
    With the tablet detached the speakers do not work at all. The headphone jack does not work at all, and does not mute the speakers when the keyboard is attached. There is also a volume switch on the tablet with does not under any circumstances.

    Code:
    cat /proc/asound/cards
    
     0 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                          HDA Intel HDMI at 0xf1118000 irq 47
     1 [Audio          ]: USB-Audio - USB Audio
                          Generic USB Audio at usb-0000:00:14.0-3.3, high speed
    It is not a hardware problem. All speakers, headphone jack and volume button work under Windows 10.

    It does not appear to be a mute problem. Alsamixer shows a master and a capture channel for the USB audio. It also shows three S/PDIF channels for the HDMI card but all are set to 0, not m, but I cannot change any of them (presumably because no hdmi device is plugged in).

    I've run through http://]https://en.opensuse.org/SDB:...roubleshooting and https://en.opensuse.org/SDB:Intel-HDA_sound_problems but no luck.

    Here is the output of

    and

    Note that the order of the cards in Yast makes no difference, indeed having both cards as 'not configured' makes no difference.

    I'm really at a loss as to what is going on. I am beginning to think that it is the USB-Audio which is not properly configured to recognise the tablet speakers properly or the headphone jack. My main concern is to get the headphones working, and the speakers muted when headphones are plugged in.

    I've been at this for four days now, so any help will be very much appreciated.

    Default Re: Sound only partially working on Thinkpad Helix

    Short update. I tried Ubuntu 16.04, and there there are three audio devices recognised, not two, `aplay -l' gives:

    Code:
    **** List of PLAYBACK Hardware Devices ****
    card 0: HDMI [HDA Intel HDMI], device 3: HDMI 0 [HDMI 0]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 0: HDMI [HDA Intel HDMI], device 7: HDMI 1 [HDMI 1]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 0: HDMI [HDA Intel HDMI], device 8: HDMI 2 [HDMI 2]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 1: broadwellrt286 [broadwell-rt286], device 0: System Playback/Capture (*) []
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 1: broadwellrt286 [broadwell-rt286], device 1: Offload0 Playback (*) []
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 1: broadwellrt286 [broadwell-rt286], device 2: Offload1 Playback (*) []
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    card 2: Audio [USB Audio], device 0: USB Audio [USB Audio]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    So it seems that the appropriate modules are not available in the Tumbleweed kernel.
