Why am I hearing some artefacts and audio distortion using SX Fidelity Amplifier?
We found that using some sound cards with SX Fidelity Amplifier may cause of additional artefacts and distortion effects in playback sound due to the time. In most all cases those effects disappeared after installing the latest drivers for the sound card. If you have same problems go to the sound card manufacturer web-site, download and install most recent drivers for your sound card.
