Hi,

The wife has a HTPC which worked of a 22" monitor..Sound came from Samsung DVD Home theatre system and an old LG Flatron box TV. I used RCA to 3.5mm jack cable from TV to PC for sound.Hence every time I switch on PC I switch on DVD player and TV and set DVD player to AUX to run 5.1 sound through PC and worked a charm as I could adjust volume through PC or on DVD player.


This past weekend she ditched the PC screen and got a HD ready 32" TV. I setup screen with HDMI cable (PC has Nvidia GT710 DDR3 card) to pc. I put the RCA to 3.5 mm jack from DVD player audio out (after an hour of figuring out) to the input 3.5mm of TV.


Now there is sound but the Realtek sound icon has disappeared on PC and on playback devices I only find the 4AAA Nvidia settings.

Why is it that when I put volume on max on PC and I can adjust the volume on TV and on DVD player but it only goes to a certain loudness level (in my case 25) on both units and the it won't go any louder?

DVD player can go 42 max but from 26 on wards it has not effect if I increase volume and the same goes for the TV and the TV can go to 100.

Is something connected wrong?Can someone steer me in the right direction please cause this is frustrating to say the least.


Many thanks and sorry for dragging this out but I know you peoples are the experts and yous can help me out.
 
What device is selected as the playback device on your Volume Mixer?
Realtek icon probably disappeared cause you are not using the built in Realtek sound card anymore, you are now using the nvdia's sound through HDMI

Yes I'm using Nvidia's sound through HDMI.But why if Nvidia/Windows Volume is at 100 the the volume on DVD or TV won't go louder from 25 upwards?

Check in the TV's Sound Settings menu if AUTO VOLUME LEVEL (AVL) is set to ON - try setting it to OFF and see if that sorts out the max volume level issue.

Also, If the PC is directly connected to the TV via HDMI - and I presume the Samsung Home Theatre is as well, there should be no need for the 2 x RCA to 3.5mm analogue audio cable any more, as digital audio is provided by the HDMI connections.

If your TV has a DIGITAL OUT (TosLink optical or RCA co-axial digital audio) connector, and your Samsung HT also has a DIGITAL IN connector, then you can feed the TV audio stream in digital format (PCM 2.0 or Dolby Digital / DTS 5.1, depending on your TV's capabilities), to the Samsung HT system, instead of an analogue audio signal.

If your new TV doesn't have OPTICAL OUT, then just take the 3.5mm AUDIO OUT analogue signal from the TV set to the AUX IN audio connectors of your Samsung HT system to allow the TV sound to play through it instead.

Okay you've confused yourself here. Firstly you're never going to get 5.1 from the PC or from the TV with an RCA cable (unless it's the old school one with the 5 separate cables). There are two options you could do.
Plug the PC directly into the DVD system, this will give you sound from the PC through the 5.1 when you've selected the Realtek to be your audio device, if you want sound through the TV you can select the HDMI.
Option two:
I've got a feeling you've somehow actually got the 3.5mm plugged into an output not an input (you never mention the brand of TV), but I might be wrong. Take the 3.5mm you've got and plug the rcas into the DVD players input, on the TV select audio output to external this should send it through the 3.5mm. This way you get all sounds from the TV through your DVD player and you've essentially got less cabling.
But you will only be getting a dolby pro-logic or neo cinema 5.1 experience as to actually get 5.1 from a PC you'd need to have it plugged in via optical or hdmi, or in the old days via 4/5 separate cables into the box.

AVL is set to off.The Samsung HT only has audio in and audio RCA's - no HDMI.
Tv I think has co-axial out (marked orange).Also Samsung HT doesn't have 3.5mm jack AUX IN only RCA audio IN.
 
I used to just take RCA to 3.5mm jack from DVD player AUDIO OUT and plug the jack in the back of my PC and it I had volume and can set it louder now with HDMI it doesn't go louder from 25 upwards.
 
Please look at my suggestion. Also tell us what TV it is.

Just check you're indeed plugging into an 3.5mm input and not an output. As most TV's come with that as an output jack, if so just plug that into your DVD receiver.

Do it the other way around - put the 2 x RCA connectors into the AUX IN connectors of the Samsung Home Theatre and the other end with the 3.5mm audio jack into the TV set's AUDIO OUT 3.5mm socket.

Then the audio stream from the HTPC to the TV set will be routed through it into the Samsung Home Theatre.

However, this will only give you analogue Dolby ProLogic II audio processing & not Dolby Digital, until such time as you upgrade your Home Theatre system to a higher specification unit that has co-axial / optical DIGITAL inputs, and you use the DIGITAL AUDIO outputs of your TV set (if available).
 
Just to be clear this DVD player HT system doesn't have 3.5mm jack socket.

Only audio out and audio in and then the yellow RCA for visual.

Why didn't you just plug into your ht system? The rca goes to it the 3.5m into the tv
