I purchased and setup my RX-V673 about three weeks ago and I have two questions for the forum that Yamaha customer service could not answer:
1) I have some audio files on a USB storage device. The files were purchased on iTunes and are m4a file type (MPEG-4). When I plug the storage device into the USB port, the AVR will not play those audio files. I have some older files that are MP3 and those play just fine, but that doesn't really help me because all of my newer files on iTunes are formatted for m4a. Since the manual says that MPEG-4 file types are supported, I am confused as to why my files won't play. Does anyone know the answer as to why they won't play? Does the AVR not support m4a? Or do I possibly have a defective USB port on my unit?
2) I have a Verizon Fios STB and Samsung UN60F7050AF 60" LED TV hooked up to my RX-V673 via high-speed HDMI cables. The TV is ARC-ready and I have that feature enabled on both the AVR and TV. I can use the Fios remote or the Samsung Smart remote to power up (or power down) all thee units at the same time. I like that when I turn on the Smart TV and start using apps, the RX-V673 recognizes this and automatically switches the audio from HDMI-2 (for cable) to AV-4 (for the Smart TV apps); when I exit the apps, it automatically switches back to HDMI-2 for the cable input. However, when I first turn on all of the units, the AVR, STB and TV all power up and I hear the sound through HDMI-2 for about 5 seconds. Then the STB powers down ... so I hit the button to turn it back on ... and then, another few seconds later the AVR switches the audio to AV-4. Which means that I then have to hit the HDMI-2 button to switch the audio back for STB viewing. Does anyone know why this happens each time I turn the units on? And, more importantly, is there a way to fix this?
Thanks for your help,
