I may have spoke too soon. After multiple reboots to verify everything was working from my last post, I powered up just now(from sleep) and got sound. At some point I folded my 2in1 to tablet mode and now, no more sound. After folding it back to a laptop, still no sound..
off to check my BIOS settings.
Fast boot has been set to minimal, it was "thorough" previously, sound is back, will see if makes a difference.
FYI, This is a brand new Inspiron 13 2in1....
Hmmm, let us know how it goes. I just tried to break my sound, I tried sleep, hibernate, restart, and flipping the screen over into into tablet mode. But, with my latest bios settings it is fixed for good, I can't break the sound which is good.
The only other thing I can think of for you is that a few weeks ago I installed the Microsoft Windows 10 Anniversary update hoping that would help it which it didn't. Then I installed any drivers from the Dell site that were newer, and of course updated the bios to the latest version. But, that didn't seem to fix it. But as soon as I turned off secure boot and then turned on the legacy rom all of my sound problems went away.
So, if you haven't already you could try updating to the Windows 10 Anniversary edition, then update your drivers (chipset, video, sound etc) then make sure your bios is set to turn off secure boot, and turn on the legacy rom. That is the order I did things in.
Here is my Windows version and model number, maybe ours are slightly different:
Windows 10 Home Version 10.0.14393 Build 14393
System Model Inspiron 13-7359
Tried to turn off secure boot, and turn on the legacy rom, but when I do that my PC refuses to boot. What am I doing wrong ? Help please.
I always shut right down when it comes to audio drivers, restart never activates the driver. It has happened to me twice. Using a cold boot works for me, good luck.
Hello, I have same sound issue on my Dell inspiron 13 i7359. And I tried to change BIOS setting, which was leading to 'no boot device found'.
So can you show some steps how to change UEFI mode to Legacy option rom?
Thanks a lot.
I have same sound issue on my new Dell inspiron 13 i7359. It seems have this issue since I upgrade Bios from 01.07.00,A06 to 1.0.8,A07. But I was aware of the sound issue caused by BIOS. I have tried so many suggestions from online. Nothing works. Until I realize the sound issue happens only when the laptop restarts. So I search the problem and find this thread.
Long story short. Here is my attempts. First I go to Dell website to see if any new BIOS driver updates and I find 01.10.00 ,A08, but it did not work either. So I began to downgrade the BIOS, to 01.07.00,A06 -sound affects, to 01.06.00,A05- it works.
I also tried to switch UEFI boot to Legacy Options Rom, but it ended up to 'no boot device found'.
Someone suggested this method working. Maybe I didn't setting BOIS setting correctly. Anyway, I am glad the sound issue is gone.
Inspiron 13 - 7353. Windows 10 Home 64 bit edition. 8GB RAM. Purchased new Dec 2015. I bought this machine for my girlfriend. Its been a great machine until recently. Audio failed recently for no apparent reason. Attempted re-installation of audio drivers from Dell with no results. All Windows 10 updates applied. First Reset PC, which did nothing. Then Restored machine with factory image. She is *** off about losing her images, favorites, etc. But those can be transferred back from backups. Waste of time when I figured out that Dell Update was what hosed the audio upgrading to the 1.10. I rolled back to the 1.06 version and audio is working fine again. I called Dell to ask why the don't remove the package from the Dell Update or fix the BIOS packages that keep breaking the audio. The Dell tech answer was to stop using the Dell Update service. I really think that is a bogus answer and that Dell should actually get some developer to fix the issue with the audio driver conflict whatever the level of issue it is. The Dell Update service should not have to be disabled. Lame. Some people have better things to do than manually update device drivers and system patches constantly just to be able to use Skype or watch YouTube videos. My girlfriend says the machine was updating itself more than she used it. I've now uninstalled most Dell software I could find.
I've tried installing latest BIOS and it solved the no-audio problem, until Dell sends another update. After the update -- which it seems is impossible to refuse -- the audio doesn't work. I've been through this three times. Why on earth is Dell sending out updates that kills the audio? I'm working on an Inspiron 13 7000 series.
