SYMPTOM: 1. In some case during BD disc playback, intermittent audio is output while decoding
2. In some case during MP3 music playback with USB drive, less than a second of
music is cut off in the beginning.
3. Under certain setting, pop noise is output when switching DSP programs.
SOLUTION: Update to the latest firmware as shown below. Download the data from Yamaha AV
Service Information Support System website / ROM Update RX-V3900 or
This new firmware improves;
1. NET/USB Playback Function
2. HDMI Video Output.
Personally v1.16 reduced 1 second video dropouts, that would occur with a Motorola Comcast Cable TV box every 45 minutes or so, to almost none now.
