Advice needed on audio/ sound problem

[teacherclaire]

My apologies for posting that once more. It's about two big screens at a school, where I've tried almost all now to get sound to the build in speakers.

 

  It's got an Android OS, some Whiteboard programs, and the sound works well on Android, even when you plug in a notebook via HDMI.

 

But the other OS, W 10 Pro does not deliver sound. NIL, Zero, niente. 

 

 I've updated all Audio drivers with Realtek ones, and I've tried different ones. I even got in touch with MS, and a technician took over remotely, but I could see that he did the same steps I had already done.

 

  I now believe that the board's OS is not compatible with the Android version that works well. I'd deeply appreciate any input what else could solve the issue, other than connecting external speakers.

 

 Thanks a lot in advance for your time.

I think I would have written, "I now believe the whiteboard's Window's version OS is not as hardware compatible as the Android version that works well."

You've contacted Microsoft, but have you tried contacting the Whiteboard's manufacturer or support people?

 

I am surprised you're running into this predicament as Android (nee "Linux") is the OS that typically relies on generic drivers that don't always run on hardware variant implementations. No matter, it's frustrating when the device works using one OS but not the other 'professional' OS.

 

If it were me, at this point, I'd probably just source a USB Sound Card and plug some external speakers into it (yes, I know that's not your preference) ...or find an electronics tech to mount said tested/working USB Sound Card somewhere internally and reroute the internal speaker wires to it.

 

ONE LAST SUGGESTION:

I've upgraded 24 units, plus five screens/ You seem to be correct as i recall a Realtek driver, better a missing, or not up to date one on another machine.

Maybe you can try taking an DRIVE IMAGE BACKUP of a working whiteboard running Windows and 'recover' that image to the problem child whiteboard. If the whiteboards are exact hardware duplicates then the copied OS should work without issue.

 

My favorite software at the moment is Macrium Reflect Free (though there are tons of others).

 

(Caveat: Creating backups is dead easy, but full recovery requires creating a bootable USB Recovery memory stick that contains a booting OS, the backup recovery application {instructions available on most Backup/Recovery support forum websites} and having simultaneous system access to the DRIVE BACKUP IMAGE previously created {though this can be on a second USB memory stick, or drive, or drive partition}).

Thanks and sorry for my late reply. The other monitors are a different brand, so i believe that's not an option using Macrium.

 

   I love Macrium and use it for many years. I think the best option is to use the speakers i have mentioned. Just plug them in when needed and unplug them when not.

 

   There's a huge whiteboard that closes in front of the screen, so it's not possible to connect them permanently. And there's only a little box that contains the Android unit, very hard to get to.

 

   It's even difficult to insert an HDMI cable at this unit, but there's another one in front.

 

  The way they built all is incredible. There's no way to get there from behind without taking the whole unit out and trying to find a way.

 

   It's not worth the headache, I'd spent days in front of it and couldn't solve the issue. Who knows, I might find a different driver than the whole Realtek package one day that works?

 

   Now it's not really about solving the problem because external speakers do the job. It bugs me that I'm at the end with my Latin. 

 

Thanks again for your time and your nice input.
