This may be obvious, but there is a microphone icon w/ a slider on the Paltalk room screen. Make sure that is up all the way too. IvanB is right, many times the "mic gain" has to be switched on as he descriibed.

For a long time I just used the little pc mic that came with the system, and it worked fine. Now I use a mixer with two mics. The two outputs from the mixer feed into a stereo jack then into the sound card.

As a suggestion, start with the simplest connection and build up from there. Each time I have made a change I have had to spend time to get it right (or in some cases go back to the drawiing board).

Hear you later....
