Slimchandi posted:I have a question regarding USB soundcards on behalf of my brother. He's using an Edirol UA25 USB sound card with a Novatech laptop (XP). Whenever he has his external hard drive plugged in, the audio skips and stutters, even if it is played directly from his laptop. I think this is to do with a latency issue over USB (had a similar thing with my PodXT) but that is where my knowledge ends. I've tried searching for help and came across ASIO4ALL, but this seems to be in reference to latency issues when trying to record and monitor at the same time, which isn't the case here, just playback. Would installing ASIO4ALL help, or am I trying to solve a different problem? The Edirol device should come with its own ASIO drivers, so assuming you're using those ASIO4ALL probably won't help. Check your ASIO buffer sizes, i have an Edirol FA-66 and the configuration utility is in the control panel. Smaller ASIO buffer size = lower latency but is more CPU intensive. I generally work with the lowest setting, but as I add in more stuff and the CPU load increases I have to increase the ASIO buffer size so I can get skip free playback. See if anything else is chewing up CPU. Also, I've heard that using a USB hub can impact on performance, as you get 2-4 devices using 1 usb port which means the USB bus gets too busy to handle the load leading to skips/stutters. So if you're using a USB hub, see if eliminating that helps.
