my audio sounds very tinny when i plug soundcard into pci max, its as iff the bass has all been lost. and just loads of trebble. i have tested the pci max card by pluging in a seperate cd player into the input, and it is fine then...

but..

i have also checked the audio output form the soundcard, when i plug it directly into my amp/speakers and it sounds fine then

the problem occurs when i plug the output of soundcard into the input of my pci card,

does anybody have any sufggestions ? please please help me and leave me a comment on this forum, thanx ever so much

It is because of your sound card. Its outputs are high impedance
and input impedance of PCI MAX is low (100 ohms) to reduce noise
as much as possible.

You could remove the 100 ohms resistors on the small audio card
on PCI MAX to increase impedance, use speaker output or use
another sound card.

Works superb :-) This is the best support ever!!!

Also if you're releasing a new soft, maybe also let the user chose between LPT and com ports. Maybe that creates problems?
Also something nice would be to be able to write message before an ID-tag like "spelar".
Best regards
