2      Appendix A – Surround Sound Playback and Recording Driver     

14

Limitations

•  It appears that multi-channel hardware peak meters are not yet properly 

supported in Windows. The 8-channel input and output subdevices 
therefore don’t have peak meter nodes, with Windows instead creating 
software peak meters. The recording software peak meter however is 
disabled when the input is opened by an application in ‘exclusive mode’.

•  Microsoft are inconsistent in their mapping of 5.1 content onto 7.1 

output devices, with Windows Media Player in particular not following 
their defined mapping and using the rear speakers instead of the side 
speakers.

•  Windows will always name a speaker endpoint as “Speakers”, with the 

driver unable to override this.

•  Windows will try to make a speaker endpoint the default playback 

device. This can be manually overridden if need be, but any driver update 
will undo this.
