Sound driver: Acer Aspire M M5-481PT, Windows 8.1, 64 bit
Acer Aspire M, Windows 8.1, 64 bit
Issue: High Definition Audio Device status: "this device cannot start. (Code 10) {Operation Failed} The requested operation was unsuccessful
Description: I noticed no sound from my machine following an automatic windows update on Nov 3
Strategies attempted to date (none have worked):
1) Uninstalled the device from Device Manager and re-started computer
2) "Updated" the driver software from Device Manager. Message shows: "the best driver software for your device is already installed."
3) Logged in to acer support -> drivers and manuals from acer.com and downloaded the audio driver for my machine: Date: 2013/10/11; Version: 6.0.1.7032; Vendor: Realtek. Attempted to install and received the message: ""install realtek HD audio driver failure !!" error code 0x00000002"
4) Ran a malware scan and removed two malicious programs. Re-attempted all of the above and no change in results.
5) Restored the systems from before the Nov 3 update and still had a Code 10 error. No earlier system restore dates are available.
Thank you for any thoughts or inputs at this point.
