    Question Mythbuntu 12.04, AMD APUs and no HDMI sound?

    As per the topic, is this the new standard? I have just invested in an AMD A8 6600 APU rig. After the usual stuffing about sorting HDMI video out, I had no sound over HDMI. Another day spent googling and reading and de-obfuscating the jargon, it seems as if we cannot do sound over HDMI anymore.

    Is this correct, or has some one found a way?

    Thanks

    Are you talking about no sound coming through the HDMI when watching TV or a movie in the frontend?

    Hi,
    Sorry for the delay in getting back here... there is no HDMI option in the sound hardware selections. I've managed to get SPDIF working, which will do.

    Nevertheless, getting sound over hdmi would be one less cable...

    thanks

    I should know these off by heart by now

    Code:
    aplay -L
    default
        Playback/recording through the PulseAudio sound server
    sysdefault:CARD=Generic
        HD-Audio Generic, ALC898 Analog

        Hardware device with all software conversions
    plughw:CARD=Generic,DEV=1
        HD-Audio Generic, ALC898 Digital
        Hardware device with all software conversions

    As stated before, I managed to get the following device to work after a bit stuffing about and turning on on-board audio in the BIOS:
    aplay -l
    Code:
    ice #0: subdevice #0
    card 0: Generic [HD-Audio Generic], device 1: ALC898 Digital [ALC898 Digital]
      Subdevices: 1/1
      Subdevice #0: subdevice #0
    Would I be right in thinking that the HDMI sound should come from the AMD APU (A8)?


    Thanks for your interest....
