Greetings, I have no problems with ending TR nor with distortion Etc. but I do not use TR for line-in recordings, preferring GW for such tasks, I use TR mainly for off-the-net material.
I am using V8.3 Pro on both my WindowsXP Home laptop and my windows7 64-bit premium desktop system and, having system sounds through the audiotech internal sound system, TR and all other sound recording software, uses the second sound card, can't remember it's details. Eventually, I am likely to update the W7 system not sure is the latest version 8.5?
