Digital language lab audio configuration

Issues (BSODs) have been reported with simultaneously running USB sound-card driven headsets and on board audio, which have been alleviated by either USB soundcard driver updates or disabling the onboard audio or both.

To be safe, we do the latter, on this screen of the Dell-Optiplex-760-bios: f12 / System Setup / Settings / Configuration / Miscellaneous Devices (you need to push button “Unlock”and issue the BIOS password to make changes):

Dual audio is also a potential source of confusion for the user. This is the reason why we prefer hiding the MS-Windows Volume control icon in the notification bar – a setting in the control panel / sound and audio devices:

We rather stir the user to the Sanako student player audio volume slider as the single point of entry – and one which can be easily seen by the teacher: see Study 1200 teacher / PC Control / Show the student player).

This comes with added responsibility for the teacher, as the Sanako student player audio volume slider does not control the WAVE volume level. Ensure proper setting of the WAVE volume level AND proper source audio levels – or use our TBA:teacher lab audio control extensions to control the WAVE levels on student computers.
