Chrome sound issue with USB Dac

    Hi there,

    I am trying to get the chrome add on to output sound with my new usb dac connected to my NUC and I am not getting there at all despite all my attempts.

    It should me noted that audio and libreelec never worked out of the box with my NUC. However I used to solve the problem by using plughw: 0,3 which redirected the audio to the hdmi output. However doing something similar in this case doesn't help.

    Audio setup:

    aplay -l output:

    aplay -L output:

    cat /proc/asound/cards output

    Code
     0 [HDMI           ]: HDA-Intel - HDA Intel HDMI
                      HDA Intel HDMI at 0xf7c34000 irq 46
 1 [PCH            ]: HDA-Intel - HDA Intel PCH
                      HDA Intel PCH at 0xf7c30000 irq 47
 2 [AUDIO          ]: USB-Audio - SMSL USB AUDIO
                      SMSL SMSL USB AUDIO at usb-0000:00:14.0-4, high speed

    Based on these, and if I am not mistaken plughw: 2,0 should work an an output device. Instead Chrome crashes and doesn't even start. In fact it crashes with anything I try as a custom audio device. Even plughw: 0,3 is not working with this installation I don't know why.

    I tried commenting the last lines of chrome strartup (the ones about pulse audio) but it didn't help. I also tried kodi mixer but it is not working as all entries appear to be unoccupied.

    All audio apart from Chome works as indented. Any leads?

    After pulseaudio support you have to use ALSA: or PULSE: prefix, e.g ALSA:plughw:2,0.

    The plugin crash if not using a prefix is likely be fixed in the near future.

    I wish I had read 'this thread' last night, when I had updated a friend's Libre system to the 10.0.1 version.

    Chrome would not launch if 'custom audio device' was selected (regardless of output device, though I was specifically attempting to use the DisplayPort output 0,3, from the same vendor-list of devices encountered by ppkstat).

    I will test 'locally', though now I have to wait until he returns from his trip to test the new 'syntax' on his...

    Don't worry. Use

    Code
    ALSA:plughw:0,3

    it will work (provided you're using this device).
