How to resolve audio issues when playing DVDs on Lenovo ThinkCentre M71z Desktop?
If you experience no audio or intermittent audio while playing a DVD movie on your Lenovo Desktop, check the volume control settings on your computer and speakers. Make sure the disc surface is clean and not scratched. Check all cable connections to and from the speakers. Use the DVD menu to select a different audio track.
Why doesn't my Lenovo ThinkCentre M71z Desktop automatically play audio CDs?
If an audio disc or AutoPlay-enabled disc does not automatically play when inserted into a CD drive on your Lenovo Desktop, if you have multiple CD or DVD drives installed, try inserting the disc into the other drive. In some cases, only one of the drives is connected to the audio subsystem.
Why is DVD playback slow on my Lenovo ThinkCentre M71z?
If playback is very slow or choppy on your Lenovo Desktop, disable any background programs, such as AntiVirus or Desktop Themes.
