No sound on PC after plugging HDMI cable


J

Jim

I have an Asus P5E3 Prem wifi motherboard running windows 7 U 64bit and
after plugging in a 10 meter HDMI to HDMI cable (to go into my TV) I do
get audio on the TV but audio on the pc cuts out, once i take out HDMI
cable sound is restored to pc, my video card is an Asus EAH6450 I know
it's old but it's passive cooling, I'm far from an expert with HDMI
stuff can anyone shed any light on why this is happening and how to sort
it please.

TIA

I don't know if you can get both or not; on my Gateway I can get one or the other, but not both. I always thought that
it was similar to speakers and headphones- plug the headphones in and the speakers don't work.

There is a trick here, but I don't know if this is always going to work.

It involves "stereo mix".

playback content ---- analog path ----+----> To computer amplified speakers (5.1,7.1)
|
+---- (stereo mix) <--+
|
|
+----- HDMI digital audio --> To TV set (2 channels)

Stereo mix (inside the analog audio Codec chip) is also known as the
"what you hear" recording option. It loops the signal back from where
it hits the speakers.

Note that, if you do this, a movie will play in 5.1 analog to the computer
amplified speakers, but only two channels (front two) will be looped back
through stereo mix. The HDMI would then only have two channels
of content, and nothing for any surround speakers (unless the TV
has synthesis and can "make" some fill sound for itself).

If you instead made the HDMI the only playback option, then it's back to 5.1.

playback content ---- HDMI digital audio --> To TV set (5.1,7.1 digital)

HTH,

Not on my amp. With headphones engaged, I have to turn the speaker
selections to off as opposed to from either A or B speaker sets. But
I've a preference for VGA connection signals, (I wouldn't buy a card
without one), preferring as soon as not to deal with HDMI, audio or
otherwise;- sound, I have to run TOS/LINK optics off the soundcard to
a dedicated amp, or traditional RCA outputs through a mixer board,
keeping both set for a simultaneous downmix to stereo only. Not that
it appears it's developed significantly as sourced for sound, all that
swiftly at TMDS 192K data rate portals, all this time since I've been
running VGA AGPs. Still, perhaps TOSLINK/SPDIF is par for anything
higher on digital protection industry cables and its connection
issues.
