I was wondering if you could help me out to understand how the voice/sound-flow for HDMI works, as it seems that I´ve misunderstood some basic things. I´ll try to be concise with the issue I´m having.The scenario:
I've got a HTPC hooked up via HDMI (vga msi 560ti
) to a LG flat TV
Works flawlessly, sound and video are perfect, couldn´t work better.
The motherboard used is a Gigabyte ga-gma880-ud2h
I also connect to the front panel of my pc with a headset for gaming purposes and when I don´t want to disturb anyone at home with music or movie sound.The problem:
I´m unable to use the microphone from my headset when connected to Front or Backpanel.
I can´t make a single Skype call, TeamSpeak or the inbuilt Steam Chat, the mic is not being recognized. I tried everything, believe me, searched on hundreds of sites, found people with similar problems, but I did not manage to solve this issue: I fiddled around with the Realtek High Definition Audio Controller, disabled front panel detection, enabled both front and rear panel, enabled mixer, played with the recording volume, enabled mic boost…still nothing – I can´t hear myself.
All I get to see is the status bar moving on the “Recording Tab”, but moving up and down in accordance with the sound played through the Headset.
I checked in the Gigabyte Forum, and I asked about this issue and I pointed out that I thought that HDMI is the culprit, but they told me not.The understanding:
Ruling out the possibility that I have a HW-issue on the onboard audio, I´m inclined to think that I can´t use the mic when my htpc connected to the TV via HDMI.
To conclude, I would need some advice to understand how the architecture of HDMI works... :
1. With HDMI, does the PC know what to do with the audio it's sending back, as video cards tend to be output only ? I I believe that I would need to send the signal as well through the video card, it would need to have additional audio-in functionality like for example with a S/PDIF cable ?
2. My msi card does not have an additional audio in connector, but it does have 2 x Dual-Link Dvi. Would the mic work, if I connect the PC through the DVI output to the LG-TV with the good old RGB cable & then, connect the motherboard with a S/PDIF cable to the back of the LG ?
3. Is HDMI connection only for output, and no input ?
Don´t know if it makes sense to get an additional Sound Card for this purpose, a budget one.
If HDMI is blocking the possibility of recording, I would switch then just the cables whenever I need them for VOIP or gaming.
Thank you all for reading my and thanking in advance for any inputs.
