No Sound is Playing / Sound is Corrupted
Updated by Russell Samuels on May 6, 2020

MediaMonkey Sound is generated as follows:

  1. MediaMonkey locates the file.
  2. Audio file is decoded by input plug-in.
  3. Equalizer settings are applied.
  4. Other DSPs are applied.
  5. Volume Leveling is applied.
  6. Sound is output via the Output plug-in.

This article discusses issues that may occur at step 6; such output-related problems will typically just result in silence or audio corruption--the tracks will not be greyed out and the problem will exist with all audio formats. If tracks are getting greyed out see 'Tracks are greyed out / fail to play'.

If attempts to play all content result in silence or corruption (but tracks aren't greyed out), the problem can be at any of steps 3-6; to diagnose the problem, first disable the equalizer & dsp plugins (via Tools > Options > Player > DSP Plugins), and Volume Leveling (via Play > Level Playback Volume). The problem could be caused by:

  1. Hardware/Driver issue. Try playing audio via Windows Media Player, Groove, or any other application. If no sound plays and/or the sound is corrupted for all apps, it can be that:
    1. The system volume is set to 0. To fix that Right click on Speaker Icon (next to clock in task bar) -> Open Volume Mixer -> Adjust volume of MediaMonkey.
    2. A physical volume control is set to 0.
    3. The headphone or speakers are disconnected.
    4. There's a problem with your sound driver (e.g. realtek), and it needs to be updated/re-installed. Check with your hardware provider.
  2. Misconfiguration in MediaMonkey:
    1. The player's volume is set to zero. Verify that the MediaMonkey volume slider is set correctly (if you don't see the player, click View > Player). If the Player doesn't feature a volume slider right click on the MediaMonkey tray icon in the Windows Taskbar tray (next to clock) and select Volume > 100%.
    2. The Player has been set to output to a different device (e.g. a UPnP player) that is set to low volume or is unavailable. To fix change the output device (Tools > Options > Player).
  3. A problem with the output plug-in. This can be related to underlying audio drivers and how the interact with your system. To fix this:
    1. If you recently performed an upgrade to your audio drivers, you may need to re-register them in MediaMonkey. In MediaMonkey, right-click on the Player and select 'Configure Current output plugin'. In the sound card list select your audio card drivers again. Accept the changes and restart MM.
    2. Try switching output plug-ins. Go to Tools | Options | Player | Output Plug-ins and change from WASAPI to DirectSound/WaveOut output or way around from DirectSound/WaveOut to WASAPI.
    3. If the DirectSound plugin yields static, you can try reconfiguring it. Go to Tools | Options | Player | Output Plug-ins, select the DirectSound plugin and click Configure. On the device tab, try either:
      • Disabling hardware acceleration
      • Switching from 'Primary Sound Driver' to another device.
    4. If the WASAPI plugin yields static or clicks, try alternative configurations.
    5. If the above doesn't work, you can try a number of alternative output plugins:
    6. If you experience playback distortion for files purchased from Amazon you'll need to Analyze their Volume again as the Volume values may be incorrect. Use Tools > Analyze Volume on affected files. Make sure Only analyze files with unknown Leveling Adjustment is disabled under Tools > Options > Volume Leveling.
  4. If there is no sound in videos make sure the correct Audio Device has been selected in the MediaMonkey Video Player Input Plugin (Tools > Options > Input Plugins).
