Precision T3400 - no audio after waking from sleep mode
Hello All,
I have Precision T3400 rungin Vista Ultimate x64 SP2 with 8GB ram and Analog Devices Integrated HD Audio controller. I have loaded the lastest Dell driver, version 6.10.x.5491, A02, for the controller. When the computer wakes from sleep, there is a white 'x' over the speaker and hovering brings up a message saying: "No Audio Output Device is Installed." I device is also missing from device manager. I've tried reloading the driver, etc., nothing seems to work but a hard reboot of the system.
Any help appreciated.
Thomas

Thanks for responding.
I disabled "hybrid sleep" in the power profiles and that seems to have helped, but not entirely eliminated, the problem.

Devices not working after standby was a problem in XP and earlier OS' but this is the first post I've seen about the problem in Vista. As audio is on a shared Interrupt (IRQ) with another device that can also be an issue. One thing to try, uninstall the Sound in the Device Manager (DO NOT uninstall the drivers) then restart the PC and when Windows starts it will detect and reinstall the sound. Sometimes on a reinstall it will place the sound on a different shared IRQ and this MAY help with the problem.
The only other suggestion is the same advice for problems on older Operating Systems, do not use Standby. The recommendation from Dell and others was to ONLY "power off" the monitor and Hard Drive at whatever delay time interval you want and not use the Standby function.
Standby (and Hibernate) were originally designed for laptops to conserve battery power.
