Windows 7 SP1 audio error

[jon71186]

It seems as though SP1 may have killed my sound. I was playing music just fine during the download process, but once it restarted my computer and finalized the update I no longer have working sound. The sound is not muted, it is enabled, and I have the correct sound device selected. After all, I made no changes to that selection prior to restarting.

I'm running sound off my motherboard. It's an Asus Rampage Maximus II Formula. I've never had to update the driver, it simply worked.

Is it possible SP1 is to blame? Would doing a system restore to right before the SP1 was installed do any harm? Will it delete SP1 from my system as a result?

Have you attempted another restart?

There are times that drivers do not get fully updated until a second restart of Win7.

I had this happen with my Wi-Fi card - no Wi-Fi upon initial reboot but after subsequently rebooting, all of the drivers loaded famously.

Yes, if you do a restore to before you installed SP1, it will be uninstalled.

Is SP1 to blame? I doubt it but I've seen more issues here with SP1 than I had ever expected to see given my experience.

If the SP 1 install succeeded, you probably don't have any System Restore points to an earlier time.

But you should be able to uninstall it outright.

But I wouldn't do that until I had more reason to believe SP 1 is the cause and that you can't repair whatever it might have done.

Have you tried uninstalling and then reinstalling your sound drivers--it may be as simple as something got overwritten or corrupted?

 

[jon71186]

I did perform another restart. And I went to ASUS' website and downloaded the most current driver for my audio device. Still no sound.

I checked system restore and there is a restore point for the installation of SP1. That should take me back to right before it was installed, if I am understanding it correctly.

Sorry for the possible double post.

Yes. SP1 creates a restore point upon successful installation (actually, before). Rolling back will restore your system to the point before you installed SP1.

 

[jon71186]

I'm going to give that a shot.

Please keep us informed. If your sound is restored, try to reinstall SP1 once more, OK?

If your sound is not restored, we'll have to look at other possible issues.

I'll be damned. My sound works. I restored and it's functional again. I'm still scratching my head though. Why would a service pack mess with audio at all? I know I sometimes get 'optional' updates through Windows Update that includes drivers for other parts of the system. But that wouldn't be rolled into a service pack, right?

I know you mentioned trying to reinstall SP1, but I'm rather leery of that, at least for now. My computer isn't going to miraculously get attacked because I don't have SP1 right away. Or maybe it won't affect the sound this time, who knows. But I'm not ready to take the chance again tonight. I'll look into it more in the morning.

Thanks for the help regardless.

Give it another shot (SP1) but install it by itself. If the issue resurfaces, you can always do another restore.

I've got a feeling this time it will work out well for you.

Glad you got your sound back. It should remain after your next update to SP1, I'm sure.

If it doesn't work (your sound) after you reinstall SP1, we'll get it figured out nonetheless.

Just installed SP1 on a Dell yesterday, and have no sound at all this morning after re-boot(s). Lovely MS, just lovely... Looks like I'm going to roll-back world...

Hello. I'm having sound issues also after installing SP1 to Windows 7 Home Premium . The problem I'm having is I'm not getting any sound via HDMI when I play a blu-ray disc. All other sound seems to be OK. When I play a regular DVD, the sound seems fine. The audio on these same blu-ray discs played just fine prior to the SP1 update. I read in the SP1 documentation that there were some HDMI audio enhancements. What were they. I don't call this issue an enhancement. When is this going to be fixed? In the mean time, I'm probably going to rollback from SP1 until this issue is fixed.

Sound issues

Sp1 installed on 2 machines yesterday. No obvious problem until it comes to sound & video. Basically no sound in WMP FLV and RealPlayer. Video or Audio tracks. Seems that all have switched to double (or maximum speed) and full volume. Of course at multiple speeds there is no sound!

Did a restore back a day and now SP1 uninstalled and audio and video are fine.

Hi. I hate to mention the obvious, but I had the same issue (i.e., no sound) after the SP1 update. For whatever reason, SP1 changed the sound output to a non-existent device. Resetting the audio playback fixed the problem.

Dell sound problem

I had the same problem, lost sound after sp1 update on my Dell. I was able to correct the problem by going to the search field and typing in troubleshooting. Select Troubleshoot Audio Playback. The system came back stating that the default sound device was correct and made the change. All works well now.
You may need to reinstall your audio driver if this doesn't work. If you do reinstall your audio driver, rerun the troubleshooting again.
Hope this helps.

I've had the same issues with no sound after installing sp1. I uninstalled and had to roll back drivers to get everything back to normal. Reinstalled sp1 and I now have sound but now it has an occasional buzzing sound, almost like a short. I've tried everything I can think of, please help.

I'm getting the same issue..

Did you ever manage to find a fix?

I tried messing with the eq.. uninstalling and reinstalling the drivers..

I even installed an audio 4, then uninstalled the onboard audio drivers, and disabled the onboard audio via the bios to see if that would do the trick.

It didn't.

Well it did a lil.. the eq on the onboard audio just wasn't working right with wmp.. I was getting a lot of distortion.. But with the audigy 4, there's just bass and treble, which is pretty easy to adjust.

Oh and the biggest win..

After installing Sp1.. my cpu started spiking at 100%.. and my onboard video magically became enabled even tho my gpu was still listed in the device manager.

After putting in a different geforce, the cpu meter went back down and the onboard video became disabled once again. But I lost a gpu within hours of installing Sp1.

Coincidence?
