How to Solve the Problem of No Sound Output from Speakers in All Apps Except Rekordbox

Question:

Why do I have no sound output from my speakers except in Rekordbox?

I have a setup with GENELEC 8330A speakers, MOTU M4 audio interface, and a MacBook Pro. I recently moved to a different room and reinstalled all my settings as before. I checked that my audio output and configuration are correct, and that my audio interface signal is on. I connected the M4 line out to the 8330 analogue in. However, I have no sound output from my speakers in any application (such as Ableton, YouTube, or Mac system) except in Rekordbox. What could be the cause of this problem and how can I fix it?

Answer:

If you are experiencing no sound output from your speakers in any application except in Rekordbox, you might be wondering what is causing this issue and how to resolve it. In this article, we will explore some possible reasons and solutions for this problem.

Possible causes

There are several factors that could affect the sound output from your speakers, such as:

  • The audio settings of your applications: Some applications, such as Ableton, YouTube, or Mac system, might have their own audio settings that override the default audio output of your computer. For example, Ableton has an Audio Preferences menu where you can select the audio device, driver type, sample rate, buffer size, and output channels. If these settings are not compatible with your speakers or audio interface, you might not hear any sound from them.
  • The audio settings of your computer: Your computer also has its own audio settings that determine the default audio output device, volume, balance, and format. You can access these settings by clicking on the sound icon in the menu bar and selecting Sound Preferences. If these settings are not compatible with your speakers or audio interface, you might not hear any sound from them either.
  • The audio settings of your audio interface: Your audio interface, such as the MOTU M4, also has its own audio settings that control the input and output levels, sample rate, clock source, and routing. You can access these settings by using the MOTU M4 Control Panel software or the front panel buttons and knobs. If these settings are not compatible with your speakers or computer, you might not hear any sound from them as well.
  • The connection and power of your speakers and audio interface: Another possible cause of no sound output from your speakers is a faulty or loose connection or power supply of your speakers or audio interface. For example, if the cable that connects the M4 line out to the 8330 analogue in is damaged or unplugged, or if the power cord of your speakers or audio interface is not plugged in properly, you might not hear any sound from them.
  • Possible solutions

    Depending on the cause of the problem, there are different ways to fix it. Here are some general steps that you can try:

  • Check the audio settings of your applications: Make sure that the audio settings of your applications are compatible with your speakers and audio interface. For example, in Ableton, go to Preferences > Audio and select the MOTU M4 as the audio device, and choose the appropriate driver type, sample rate, buffer size, and output channels. You can also test the sound output by clicking on the Test Tone button. If you hear a tone from your speakers, then the settings are correct. If not, try adjusting the settings or switching to a different audio device.
  • Check the audio settings of your computer: Make sure that the audio settings of your computer are compatible with your speakers and audio interface. For example, in Sound Preferences, select the MOTU M4 as the output device, and adjust the volume, balance, and format as needed. You can also test the sound output by clicking on the Output tab and selecting a sound effect. If you hear the sound effect from your speakers, then the settings are correct. If not, try adjusting the settings or switching to a different output device.
  • Check the audio settings of your audio interface: Make sure that the audio settings of your audio interface are compatible with your speakers and computer. For example, in the MOTU M4 Control Panel or the front panel, set the input and output levels, sample rate, clock source, and routing as needed. You can also test the sound output by using the Monitor Mix knob and the Monitor button. If you hear the sound from your speakers, then the settings are correct. If not, try adjusting the settings or switching to a different clock source or routing.
  • Check the connection and power of your speakers and audio interface: Make sure that the connection and power of your speakers and audio interface are secure and functional. For example, check that the cable that connects the M4 line out to the 8330 analogue in is not damaged or unplugged, and that the power cord of your speakers and audio interface is plugged in properly. You can also test the power by looking at the LED indicators on your speakers and audio interface. If they are on, then the power is on. If not, try plugging them into a different power outlet or using a different power cord.
