Macbook Pro Right speaker isn't working

They speakers are broken and no longer working and need to be replaced.

Having trouble with your HDMI port not detecting your monitors or TVs all of a sudden? Go to system preferences -- Click Display - Hold down the alt option key -- click the newly revealed Detect Displays button on the bottom right of the Display settings panel. That should solve 90% to 99% of issues if your cables and Macbook pro are good. This happens to me all the time when I try to plugin to a 4K tv at the office which is the exact same model I have at home. The one at home works while the one at the office never auto detects. If this did not fix your issue, check that your Macbook Pro HDMI port and HDMI cable ends are clean and free from debri and not damaged, double check that your HDMI cable is working on other devices, make sure your TV or display is powered ON, check that your HDMI cable is securely and fully seated, check that you're on the right input on your TV or Display, make sure the cable is not too long because HDMI has length limits depending on the cable and devices, and then force detect display again on your Macbook pro. If this still did not work, when it worked before. It's likely that your Macbook Pro, TV, or Macbook Pro HDMI port is acting up. I'd recommend taking in your Macbook Pro to the Apple store at that point to get diagnosed. Hope this helped

go to system preferences then click on sound, then make sure the "use audio port for" is set to sound output.

Hi, I had this problem too but thankfully I figured it out after a investigating a few settings. I was very frustrated because the light came on and the buttons would manipulate my MacBook Pro and MacBook sound, but nothing came out of the speakers. Solution:1.) Click on System Preferences, 2.) Choose "Sound", 3.) Select the "Output" button in the middle of the top bar, 4.) in the selectable menu, choose USB (of course your speakers must be plugged in for this to show). Tada! You can even balance the Left and Right speakers in this menu. Hope that works for you too!

This has also happened to my Macbook Pro - nothing would work, so i basically pressed the power button until it closed down and waited a few minutes and turned it back on. The problem ( touch wood) did not come back again yet. Good luck!

Go to the system preferences from by clicking the Apple->system preferences menu. check the mute option is on or not. Also check the other options 

Connect external speakers, headphones, or optical digital audio equipment. The headphone / line output jack accommodates optical digital audio output, analog audio output with a 24-bit, 44.1-192 kHz D/A converter, digital audio output up to 24-bit stereo and 44.1-192 kHz sampling rate and supporting encoded digital audio output (AC3 and DTS). For analog headphone / line output a standard audio cable with 3.5mm metal plug should be used. For digital audio, a standard Toslink cable with a Toslink mini-plug adapter can be used.
You can find the Digital to Analog converted:

Sounds like the cutout switch in the output jack is stuck open, it is a techy fix sorry (at least it is not a board failure)
