LMDE 2 - Lenovo T430 - mDisplayport to HDMI no audio

Postby ronaldtimmermann » Wed Mar 15, 2017 11:58 am

Hi there,
I'm running LMDE 2 on a Lenovo T430 laptop on current kernel: Debian 3.16.39-1+deb8u2

I'm trying to connect my laptop to an external screen via HDMI. As the T430 only comes equipped with a mini displayport, I've had to use a mini-displayport-HMDI-cable/adapter. The adapter supports sound as does the mini Displayport on the T430. I have picture/video, but alas no sound. When right-clicking the sound-preferences tab I see no choices to choose other hardware than "Built-in Audio" choosing 'Digital Stereo (HDMI) output ..*' does nothing to provide sound.

Actually, now that I've toggled the 'Settings for the selected device' on 'Hardware' eventhough I toogle it back to 'Analog Stereo Output' the device figures as 'Disabled' and I get nothing but static through headphones.. 'Output' tab has 'Dummy Output Stereo' the choose..

What do I do next to solve this/these issue/s?
