This is an issue I've been troubled by for several months. I used to be able to monitor audio tracks as I recorded, through headphones in the computer headphone socket, without problems, but since I upgraded my system it’s been impossible and any advice would be welcome. Before, I had a Compaq laptop with XP and Powertracks 9. Now I’ve got an Acer Travelmate 6292 with Vista and Powertracks 12. I record guitar, voice and harmonica audio tracks via a speaker/amp with a line output. The Acer has both mic and line-in sockets and the audio is processed by a Realtek system that came with the computer. Realtek does not appear to want to record and output audio simultaneously and while I can successfully record audio tracks on to PT, despite several email discussions with PGMusic, Acer and Realtek, I still can’t monitor audio input. The best that Realtek have managed is what they call a software solution that plays back what’s being recorded with a delay of about a second, which just confuses. I’ve tried installing ASIO drivers, but I get no audio input at all with them. I seem to have tried all the possible combinations listed under Options/Preferences/Audio. I can’t easily use my speaker/amp to monitor, as the levels needed to get a sufficiently high signal on the Acer are unacceptably loud coming out of the amp. For the moment I’m resigned to recording without monitoring, and without audible amplification, which is just about possible with a semi-acoustic guitar, but was impossible with a solid. I can also just about monitor output from the amp direct using ancient headphones with their own volume controls turned down, in the amp’s headphone socket, but it all seems an unfortunate, frustrating lash-up and a significant step backwards when I could do it successfully before on supposedly less advanced equipment.
