Please help - speaker pop

@Aphelion, thanks for the help. I do have the x64 bit version of the driver your link was for. I tried changing the setting described in your post and the "pop" still exists. Im thinking I need the vista driver needed in the link "no audio driver yet from hp" but the one for my laptop?

thanks for the help

No problem.

Speaking of "pops" an odd thing just happened to me. I had been away from the computer for a while and it has gone into sleep mode. This system is used for music production and I have a set of studio monitors + sub hooked into a 24 track mixer, all of the PC audio outs as well as external synthesizer modules/keyboards are also in the mixer. When the PC came out of sleep mode there was a loud pop. I usually monitor through phones so I usually don't hear this as they're not on while booting up or shutting down. I wonder if this is what you're hearing? It's fairly loud and definitely sounds like the battery/speaker test.

I think I know what it might be.

Right click on the Microsoft speaker icon in the taskbar.
Select Playback devices.
Select Speakers, then the "Properties" button.
Select the Enhancements tab.

Scroll down... if "Loudness Equalization" is enabled, disable it.

Might have to reboot, depends, there may be a check box for "Immediate Mode", enable that first.

The loudness enhancement is a compressor, it will try to level the audio signal, loud passages of music/speech..etc will be brought down, soft passages will be brought up.

When the computer is coming out of sleep the audio system is powered down (new green systems do this) so a small "pop" may be normal.. depends on if the output is buffered. If "loudness eq" is enabled it's hearing dead silence so it has brought the gain up, when the pop occurs, it's amplified far beyond it's original level.

Well, that's my theory... looks great on paper!

Give it a try.

I checked and "loudness equalization" wasn't selected, thanks for the suggestion though!!

Ahhh.. drat! oh well.

I'll have to see what caused the pop in my system.

young,

please let me know if you are able to resolve this. I've been having the same issue. I also have an hp laptop, but it's an older dv2000. I came from XP, & I had no sound issues until I installed Windows 7. I can get the "pop" noise to go away with the default driver that windows installs, however, with that driver I lose sound every time I resume the computer from sleep, & I can't get the sound back unless I reboot. With the original conexant driver that hp uses for my model, the "sleep" issue goes away, but the speakers pop quite often - normally after coming back from sleep, & also when not using sound/audio for a certain (unknown to me) amount of time. It seems like if I don't use any sound for about 15-20 min, whenever I initialize sound I hear the "pop" noise. It's as if, as I think someone else suggested, windows 7 turns off the speakers after a set idle time & the noise we hear are the speakers turning back on. I experience the noise through headphones as well.

I have searched & searched but cannot find a solution that works for me. I have tried so many different drivers that I can't remember which ones I haven't anymore. If it is windows turning the speakers off, I'd think there would be a way to disable it. I've sifted through every power option & (obviously) haven't found a setting that fixes this problem.

After dealing with this problem for several months, I'm about ready to go back to XP over it. I love windows 7 but this issue has snowballed to the point that it's like driving me insane that I can't fix it.

I'm glad I found this thread b/c it's recent & people are still posting - I hope someone out there can find a solution...

Yeah I'm sure we're not alone as after searching It seems as most DV7 models have this same issue. What gets me is that some people get there's fixed with HP drivers, I unfortunately have tried most of the ones I am aware of. Some people have had luck with vista drivers, but when I go to the HP web site and put my model in the driver search critia and put windows vista as my operating system I only get like 5 drivers in results,, and known of them are sound drivers. When I put windows 7 in the search criteria I get like 20 drivers back in the search results, but the sound driver causes the same issue as original driver.

Kind of a side note, but I've noticed that audio does not work properly with camstudio while using microsoft's default driver, but audio works fine using the conexant driver hp originally supplied with my laptop. On the speaker pop issue, both the xp & vista drivers supplied by hp have the "pop" issue. HP has not offered a windows 7 audio driver for my model.

caesar, have you had any luck yet?

Just bought a dv7t-3300. Out of the box it pops in the base speaker at startup and restart. In fact, it pops after exiting bios. My bios clock also randomly resets to some time and date. The pop after bios exit woudn't indicate a windows driver. It pops with or without battery use. I sent it to HP repair. They confirmed the pop, replaced the MB (with upgraded bios) and drive, and returned it as repaired. It still pops exactly the same. Idiots. This indicates a bios or chip control problem I would think. HP is probably in deep with this screw up. I thought of putting a scope across the speaker and matching a cap to the frequency, although the system should filter a high frequency out of the bass.

Very strange. I have neither of those issues & I'm actually scratching my head a little bit as to how/why it's popping when you're exiting the bios. My system is much older, but I know my hp2000's bios has a system beep option that can be turned off. Even if you have that option, it probably wouldn't do anything (b/c it's tied to the motherboard beep), but you could try it nonetheless.

When you say "base" speaker, do you mean base as in the laptop's built-in speaker, or bass as in the subwoofer? If it's the subwoofer, then the issue might not be with windows. I used to have an external 5.1 system, & I remember the subwoofer making a noise when being powered on/off.

If it's the notebook's built-in speaker, I'd be calling hp again & complaining. There is no excuse for them to sell a laptop with windows 7 pre-installed that is having audio issues like that. While I'm still upset that I'm having speaker issues, it's more understandable for me b/c my laptop was originally shipped with xp. It sucks that hp hasn't released a windows 7 driver for my machine (& they probably never will), but it sucks even more that microsoft's generic driver for my device also has issues. I never had a single issue with XP, audio or otherwise. It seems like microsoft always takes two steps back to take one forward. Hopefully a service pack will remedy a lot of the audio issues.

But I cannot understand why hp would sell a laptop knowing that their hardware or drivers are causing audio issues with the pre-installed OS. If you plan on keeping your notebook, or if it's too late for you to refund it, I'd be pretty much demanding a free upgrade of some sort.

Sorry for the length/emotion...
