Audio lockups on HPE-450f with onboard Realtek
Posted on 2011-02-17
I've spent several days tracking and trying Internet leads on audio problems. (There are many, particularly for onboard Realtek audio!) Few seem to apply, in that my audio seems to start out working okay, and the configuration looks fine.
Perhaps someone will have a new idea for me? Short of reinstalling Windows.
Audio output appears to work fine after a computer boot/restart. Plays youtube and system sounds. However, trying to open Playback Devices or Recording Devices from Speaker in toolbar appears to produce no response. Trying to open Realtek Audio Manager from Control Panel appears to produce no response. Then after about ten minutes (literally!) they do open up and appear to behave properly. Devices that use audio, such as Skype and WebEx appear to die. Even shutdown hangs with the message that Explorer can't play the logoff sound!?
Windows troubleshooters say that devices are working properly. Windows Audio and Windows Audio Endpoint Bridge services are running. However, on attempting to restart Windows Audio it eventually says it can't. Error 1053. Did not respond to stop request in a timely fashion.
Although DxDiag reports "No problems found," it fails to complete its scan.
Fairly new HPE-450f. Seemed to work fine for several months, then after some upgrade -- don't know if Windows or user program install -- began observing the behavior. Tried going back to earliest Restore point with no benefit.
Installed latest Realtek HD driver, both from HP support site, then from Reaktek site. Appears to work okay for a while, but after concluding a Webex conference, for example, then any following audio interactions are frozen. Eventually Webex won't even start an audio conference after a system restart.
