somehow got it to work , changed the sampling rate and audio system to windows wasapi and it worked. now to figure out how to best make use of it.

Hi jmsms,
Glad you got it to work!

For lower latency trying choosing WDM-KS and using your Blackstar amplifier as the output device instead of the Realtek card.

Some users prefer the ASIO drivers that are available for some sound cards. There is a guide to using ASIO with jammr here:
