I just bought and installed an ESP1010 sound card and everything went well as expected. However, once I tried to record vocals to test the microphone it will only record in either the Left Channel in Input 1 (XLR Input) or the Right Channel in Input 2 (XLR Input). I have installed the PCI card with the latest drivers but nothing changes.
I need to record in stereo, so how can I fix this problem?
