Please help - speaker pop

OK, the update did eliminate the "loud" popping sound when shutting down. But, there is still a popping sound (but this sound is now faint). I have the "faint" popping sound during both start up and shut down. In fact, when starting up it popped several times instead of just once. Please continue your fix HP.

Updated the Bios on reccomendation of HP email support - updated to version F.1B (sp48570.exe 04/23/2010) - this has effectively solved the POPPING issue (along with audio driver update above) - there is still a very slight popping sound... more of a 'click' as the speakers power up/power down, but definitely nothing at all like it was before. As stated above, there is still a minor issue during start-up/shutdown but this is 99% there.

*note; this is for HP pavillion dv7-3170ca - your computer may have a different bios update

Oddly enough, the slight 'click' on startup and shutdown now sounds like it's coming from the left speaker (as opposed to the speaker underneath the computer... just an fyi.

I've had similar experiences with the new audio driver, but I haven't tried updating the BIOS yet. I'm also noticing some odd audio reverb effects with Trillian Astra, so some work is still needed with the drivers. Good to know they're moving foward on the issue, though.

The site that I got my information from was: Audio Device Class Inactivity Timer Implementation (Windows Driver Kit)

My "IdlePowerState" was set to 04, which is D3Cold in their terms; I changed it to 03 (which I assume is D3Warm, and which I also assume is the pre-Win7 setting); it made no difference. Since this is a desktop and not a laptop, I ignored the ConservationIdleTime setting (since that applies to running on battery power), and I increased toe PerformanceIdleTime from 012c (or in the registry, "2c 01 00 00") which is 300 seconds, to "2c 0f 00 00" which is about 67 minutes. and so far that seems to have fixed it. I assume if I'm idle for over 67 minutes and then I get an email, it'll "pop" again, so my choices are to change the IdlePowerState to 00, or increase the PerformanceIdleTime to an even bigger value.

Jabba, if you were standing next to me right now, I'd give you a hug! I have been so frustrated with this issue until now. I suspected the problem had to do with timing out/power-saving, because the pop always occurred after non-use of audio for what seemed like a period of 5-10 minutes. Clearly my google skills are not up to snuff, because I have been searching for information on this for a long time but came up empty. Thank you thank you thank you.

ps: my perfomanceidletime & idlepowerstate keys contained the same values as you.

I was having the same problem discussed here, a popping sound when Windows caused the audio to go into a low power state. I am using the digital output (SPDIF) from my ASUS P7P55D motherboard. It has a VIA audio CODEC. The driver I was using was from the ASUS website. I tried several of the older versions that were available from ASUS.
Adjusting the Device Power Settings in the registry as discussed here worked until I rebooted the system. The settings would be reset on reboot. Going into sleep mode would not change the bios settings.
Finally I tried downloading the drivers for my audio setup directly from the VIA website. This driver configuration has completely different Device Power Settings. It fixed my problem
