Re: DTS SOUND--Failed to find APO Endpoint?

I think uninstalling and reinstalling it would be a good idea. You can find the downloads available on your model's support page.

I have tried uninstalling DTS Studio Sound Application and reinstalling it multiple times and it still has an error message of "Failed to find APO endpoint".

Hey,

 

I had the same problem.Makes sure that you have downloaded the latest Realtek HD Audio Driver before trying to install the DTS Sound Utility. Also,make sure that the RealTEk Audio driver was released before the DTS Driver you are trying to download. These are the 2 drivers I installed and it worked for me.


Realtek Audio DriverPosted Date: 2013-09-18 | Version: 6.0.1.7023 | Size: 218.09M
DTS Sound UtilityPosted Date: 2013-09-18 | Version: 1.1.27.0 | Size: 8.13M

 

Good Luck!

Re: DTS SOUND--Failed to find APO Endpoint?

Hi everyone, I'n having the same issue on my s75t-a7217. Tried updating, uninstalling and reinstalling but the same result. I've had issues with the HDMI too but it resolved on its own I think but the DTS just happened today. I'm getting tired of all this. Toshiba has let me down. Now I think I should've gone for the HP Envy. I'm still open to all suggestions and willing to try them. 

 

Thank you.

Re: DTS SOUND--Failed to find APO Endpoint?

Are there any Toshiba staff here that have any further answers perhaps? My DTS Studio seems to have been corrupted or deleted. 

 

My sound went out a couple days age and after some research I uninstalled DTS Studio from the programs list. It was nowhere to be found in the device manager.  I attempted then to download the program from the Toshiba website and reinstall, but at the end of the install it gives my a message: "This product does not support DTS Processing," and cancels the install. I have tried finding DTS in the sound window and have tried clicking "show disabled devices." Nothing works. Its as if my sound device has simply disappeared. 

 

My laptop is a Satellite S55t-A5337. Any help would be much appreciated.

Re: DTS SOUND--Failed to find APO Endpoint?

Sorry but this is absolutely ridiculous. I have been on the phone with countless different customer service people both from and outside of Toshiba and nobody has a remote clue what is going on here. When I spoke to the Toshiba people they could not even navigate me to BIOS even after telling them all my machine specs and operating system!  I know that I am not the only one with this audio problem and it really limits what I can do with the computer. Its not very good customer service to simply say "I don't know, just send it in". This is not an option for me anyhow since I purchased the computer in the US and work in Norway. If there is anyone that has gotten past this APO endpoint/ audio device problem please speak up!

I'm having the same exact problem with a satellite e45t-a4300, just started a couple of days ago. Just joined the forum and I'm posting in here because I'm also looking for an answer

Re: DTS SOUND--Failed to find APO Endpoint?

I've had the same trouble with the Failed to find APO End Point too!  I've tried uninstalling & re-installing with the same results as you guys! NADA!   The only other option I can forsee is to completely return the laptop to the original configuration.  Although, there is a DTS Software download online. It doesn't have the "Studio" included in the name.  It does say it is for Toshiba Laptops.  I'll try to find an answer to this problem that Toshiba seems to ignore!

 Uninstalling & re-installing does nothing to fix the DTS Sound "Failed toto find APO Endpoint".  It has actually made it worse!  Now I don't even get that error message! Thanks for the LACK of TECH SUPPORT TOSHIBA!

Same problem on a S55-A5176.

Mr Moderator, why doesn't Toshiba just post here a sequence of steps to solve the problem instead of referring every one of us to call support...which invriably wants $99 to fix anything?

 

I would think a procedure that would completely uninstall the existing program/driver, and reinstall a good one, would solve it.  If there are steps that a suport technician can do to fix it, then those could be posted here.

Re: DTS SOUND--Failed to find APO Endpoint?

I'm not a support technician, and I don't know what they would tell you. What I do know is that it sounds like a support-related question, so technical support would likely be able to help with that.

Re: DTS SOUND--Failed to find APO Endpoint?

Well, I suppose ANYTHING needingto be done to a conputer can be called a support-related question, no?

 

I would also think that a support-related problem being experienced by numerous people should have the solution publicy posted rather than telling everybody to call for (usually) paid support.  One-off problems of course are what support is there for, and I have paid for Toshiba support before...because my problem was not findable on the web--thus was a one-off issue.

Re: DTS SOUND--Failed to find APO Endpoint?

Amen Brother! We get updtes from toshiba that screw  up our sound. They don't post or tell us how to fix the problem on here, or any where else. Then we are told to call Toshiba for their oppiion, for an unknown cost for the problem they created!

Re: DTS SOUND--Failed to find APO Endpoint?

It just occurred to me...they are telling us to call support--implying that "support knows the answer and can fix your problem."

 

So, why don't they just post that fix here? 

 

No, better to collect $99 from hundreds of people.

Re: DTS SOUND--Failed to find APO Endpoint?

This is a peer-support forum. If anyone knows the fix, they can post it. I don't know how to fix this problem, so I suggest calling support. I'm not a support agent.

Add me to the list..after updating Toshiba IDt stuff suddenly no more sound control. The same APO  endpoint......as I can see Toshiba doesn't seem to be interested in the problem it caused..
