AddAudioModes - Builds and removes audio modes that AHI can understand
FILES/M, QUIET/S, REFRESH/S, REMOVE/S, DBLSCAN/S
FILES - Specifies which descriptor(s) to be added to the current mode list. QUIET - If specified, will suppress error and output messages REFRESH - Scan `DEVS:Audiomodes' and add all descriptors found there to the current mode list. REMOVE - Flush the current audio mode list from memory. DBLSCAN - Will open and then immediately close a native, double-scan screen. On some systems using a graphic card, this will enable >28 kHz sample frequencies with the native audio. You need an appropriate monitor driver in `DEVS:Monitors' to make it work.
