I have absolutely no sound with this card, in PVR2 sound works ok.

I tried to remove all leadtek software, turn off "Automute if no Tunersignal".

I use 4.1.16 in Vista x86.

The way DScaler changes volume does not work anymore in Vista. You will have to change this somewhere in the Windows Control Panel IIRC.

There is no problem with volume control etc

Support for this card is new in 4.1.16, image is just fine, but absolutely no sound (trust me).

Your card is Analogue/DVB combo. The tuner needs an special init sequence to switch between this two modes what is not done in DScaler atm. I added this info to the cardini file in hope it is usefull for composite or svideo input only. What I like to know is if you can tune in Dscaler between stations?

Audio on Vista is an other story like Rob said.

Tnx for reply.
Yes, in 4.1.16 everything except sound work fine - card detection, tunning channels.
4.1.15 was totaly broken on this card, even if I selected tuner manualy.

Tuner works? That makes me wonder...
For audio take a look at here:

Don't know if that helps for Vista.

Remote / PVR / Direct Burn apps closed?
Can you find in Dscaler's folder a file "CX238801.txt"?

Again: There's nothing wrong with volume setting.

OK.

You can connect the capture card to an amplifier or an mp3 player to the sound card to see where the problem lies.

If sound works with PVR2 application and volume setting is correct, then where else can be a problem? Only in the capture card imho.

What I like to know if the chip is only muted like it is on many cx cards done from outside DScaler by wdm driver. Interesting is the register AUD_VOL_CTL but seems to be forgotten by accident in file CX238801.txt.

But you can try RegSpy. Get it from here:
http://sourceforge.net/project/showfiles.php?group_id=7420

Please let us known the value of this single register (nothing else is interesting) when your PVR app is running and when DScaler is running.
