Troubleshooting (continued)
I can't hear any sound when I'm playing music.
Make sure the audio cables are properly connected.
If the audio cables are connected to your TV, the TV must be on to hear
any music.
If the audio cables are connected to your stereo, make sure the stereo
is on and you have the correct stereo input source selected. If you are
having trouble selecting the correct audio source, refer to the instructions
that came with your stereo.
Some of my MP3 and WMA files don't appear.
The DSM-320 supports the most common music file formats. However,
there are almost an infinite variety of bit rates and sample rates. If a file
does not appear on the receiver, it most likely uses an unsupported rate.
The files may be copy protected. To share your files, turn copy protection
off when you rip them (Note: WMA DRM files can be played by using
Windows Media Connect Server software, see page 25 for details).
The following MP3 sample rates are supported:
4, 8, 16, 22.05, 24, 32, 44.1, 48, 88.2 and 96 kHz.
For best results, rip your MP3 files at 128 kbps or higher, with a sample
rate of 44.1 kHz.
I am not able to play certain media files.
The DSM-320 supports most industry standard file formats but even
supported file formats can be encoded in ways that are not supported.
Try exporting media with different encoding settings or using different
software applications to encode your files.
