Before os version .78 You can send it one of four strings to change it's audio rate playback: 0ar(carriage return) makes it auto detect the video's audio rate. 1ar(carriage return) makes it playback at 32KHz. 2ar(carriage return) makes it playback at 44.1KHz. 3ar(carriage return) makes it playback at 48KHz. 4ar(carriage return) makes it playback in Dolby Digital 5.1 mode at 48KHz. (carriage return) means insert 0D hexadecimal or press Enter at the keyboard. Once you reboot the machine, the DVM2 returns to analyzing the lowest numbered file in the harddrive for its audio playback rate. After os version 78 0AR - MPEG Audio Mode, auto-detect sample rate and SID of every file searched and DO NOT try to search AC-3 clips with auto-detect enabled (see Operational Notes below). 1AR - MPEG Audio Mode, 32KHz, use SID of C0 (upon bootup, sample freq and SID is taken from lowest numbered clip) 2AR - MPEG Audio Mode, 441KHz, use SID of C0 (upon bootup, sample freq and SID is taken from lowest numbered clip) 3AR - MPEG Audio Mode, 48KHz, use SID of C0 (upon bootup, sample freq and SID is taken from lowest numbered clip) 4AR - AC3 Mode, 48KHz, SID = 80 5AR - Go back to MPEG Audio Mode, set sample rate and SID from next clip that is searched. (Thus is different from 0AR, in that it keeps that setting after the first search)
