Appendix B – Trouble Shooting
1. Why I cannot enjoy the 24-bit/192kHz high definition audio quality from
AS372?
You may use AS372 under USB Audio mode 1.0, and it only delivers
16-bit/48kHz audio quality. Adjust the slide switch on the bottom of AS372
to U2 position and setup AS372 in USB Audio Device 2.0 mode. Unplug and
re-plug AS372 USB cable to computer system.
2. Why I need to install drivers under Windows environment?
Windows does not have the native drivers for gears which comply with
USB Audio device 2.0. Therefore, you have to install the drivers from the
bundled installation CD.
On the other hand, if you are running the latest Mac or Linux OS, they
already have built-in native drivers for USB Audio Device 2.0. AS372 is a
real plug and play device to execute the drivers automatically.
3. System advises to install Microsoft Frame Network during installation.
.NET Framework 3.5 builds incrementally on the new features added
in .NET Framework 3.0. For example, feature sets in Windows Workflow
Foundation (WF), Windows Communication Foundation (WCF), Windows
Presentation Foundation (WPF) and Windows CardSpace. In addition, .NET
Framework 3.5 contains a number of new features in several technology
areas which have been added as new assemblies to avoid breaking changes.
You can download it from
http://www.microsoft.com/download/en/confirmation.aspx?id=25150
4. If I do not install the drivers, can I use AS372 as a multi-channel USB Audio
device?
Yes, you still can use AS372 without any installation. Please switch the
button slide switch to U1 and setup AS372 in USB Audio Device 1.0 mode.
5. Why I cannot use my AS372 when it connects to a 4-port USB HUB.?
AS372 needs fully 500mA from the USB port. The HUB might not provide
such big current to AS372. Please connect AS372 to a PC system USB port
directly, or connect it to USB HUB that has power adaptor.
