What are the minimum hardware requirements?

The USB Audio class uses isochronous transfer mode to transfer the audio signals on USB. Early USB implementations and chip sets did not support isochronous transfer mode correctly and had a couple of other issues. Therefore, it is necessary to define minimum chip set requirements. However, most users don’t know which chip set is inside of their PC or laptop and it may not be easy find out this. Hence, it makes sense to define a limit for the age of the computer. Based on this AMI defines the minimum PC hardware requirements as follows:

  • PC or laptop manufactured after January 2006
  • Intel Core 2 @1.6 GHz, or AMD equivalent
  • 1 GB main memory

It is important to note that there is no guarantee that USB based audio streaming works on any PC that fulfills the above requirements. Because there are so many different PC configurations there is always a risk that hardware and/or software issues will cause problems. Some examples are given in the next section.
