Mine was going distorted on my laptop very often. So often, that I could rarely get through a 4 minute song! Totally unacceptable. However, this has not happened on my desktop computer. So for now, I can just use my desktop. Ultimately when I have more time, I will have to troubleshoot the laptop.
I have been using the most recent driver since I thought I had to use that version if I am running Windows 7 64-bit. Maybe I should try the older driver instead.
I decided to try uninstalling the 1.48 driver and installing the 1.22 driver.
The 1.22 driver works much better on my laptop. I will see how long it lasts, but for now, I have been playing 192/24 FLAC files over my network without any problems. With the 1.48 driver, the sound would have gone distorted or had drop outs many times by now.
