Internal Speaker Output Device Missing

If the internal speaker does not work after enabling it through the Device Manager, the internal speaker may be defective and non-functional. In this case, usually, a motherboard replacement is merited, as it is very difficult to replace the internal speaker on the motherboard. Apple, in their wisdom (I must assume), have made the Sound preferences on OS X somewhat limited. There is no immediately obvious way to play sound through multiple devices, and no way whatsoever to play sound through headphones and the internal speakers simultaneously, or, God forbid, to direct system notifications sounds to one, and standard sound output to the other. If multiple audio output devices are available, check that you have the appropriate one selected. Here's how: Select the Speakers icon on the taskbar. Next, select the arrow to open a list of audio devices connected to your computer. Check that your audio is playing to the audio device you prefer, such as a speaker or headphones.

Why does my mac not have internal speakers

I have a Bose Soundtouch 300 sound bar that is connected to my OLED Gallery series TV (2020) via HDMI ARC. I set it to HDMI ARC so the sound comes out of my soundbar instead of my internal speakers. After a while I turn off the TV and later on turn it back on. When I turn it on, sound starts coming out of my sound bar, then switches to the TV, then switches to the sound bar, and back to the TV where it stays. Then I have to manually switch it to HDMI ARC to output sound from my soundbar. Is there any way to prevent this so it just defaults to HDMI ARC and never outputs through the internal speakers?

Does the Bose 300 turn off with the TV or does it remain powered on?
Hi all, I seem to be having a similar issue. I have the LG OLED 77GX and a Bose soundtouch 300 connected via the HDMI ARC. I can manually switch the sound output to the HDMI ARC and everything works great, but the next time I power on the system, the settings will revert to internal speakers, requiring me to manually switch back every time. The sound at does indeed power on/off with the TV. If I connect the sound bar via optical, the issue is corrected, but honestly would like to take advantage of the benefits of HDMI ARC if I possibly can. Any advice/insight on the matter would be appreciated. Thanks!
I’m having the same issue, with the same soundbar. The soundbar does switch off with the tv but tv keeps reverting to internal speakers. Any possible solution?

My SoundTouch does turn on and off with the tv. Exact same issue with hdmi arc switching back to internal speakers.
Exact same problem though i'm not totally sure if it keeps switching between internal speakers and sound bar. The sound bar comes on when i turn the tv on when it was last on HDMI ARC but about 2 out of 3 times, it quickly stays on internal speakers. 1/3 of times it works. This has only started in the last couple of days for me. For the last 4 weeks or so there was no issue at all and it worked exactly as it should
No one has any clue why the ARC isn't working properly? Or how to set the TV to default to ARC? It wouldn't be so bad except for the LG menu makes you do a lot of clicking to change the output back to ARC
I have the same issue.
soundbar turns on & off with TV but tv reverts to internal speakers every time it’s powered on.
Any solution to this?
my soundbar is a JBL unit. Worked fine with my last LG TV.

SAME ISSUE, but with a LG SN6Y soundbar connected via HDMI ARC (only). Soundbar keeps reverting to OPTICAL upon power-up, and therefore no sound because there is no optical cable connected.
I have a CX 65” with the same problem of switching between soundbar and internal speakers, while using HDMI ARC. Found a solution elsewhere on this site. When I turn on the soundbar FIRST, then the tv , then it works as it should. I use a Harmony smart control to have a “delay” on starting the tv. This works for cable box. When I try to switch to Netflix or another app, I get no sound. Go figure.
'After much tinkering, I was able to get soundbar to work with Netflix. Had to change settings as follows:

“All Settings”
“Sound”
“Additional Settings”
“Digital Sound Out”
From “Auto” to “Pass Through
Now Netflix works with soundbar (and Harmony remote)
Remember to turn soundbar on FIRST, then tv.
Hope this helps someone.
