Hi,
I am using an Elitebook 820G1 with an external monitor HP Compaq L2206tm.
The monitor is also not showing up in Sounds>Playback as of now.
But when it does show up in Sounds, it can play sound from the laptop.
Problem is sometimes after reboot or wake up from sleep, the monitor drops off from the Sounds panel.
I tried uninstalling Intel (R) display audio driver from Device Manager, and then do a scan for hardware changes to reintall the driver, I get a message "Device driver software was successfully installed."
May I know where can I download Intel (R) display audio driver for HP Compaq L2206tm / Elitebook 820G1?
And what can I do to keep the monitor stay on the Sounds panel?
Please help, I have googled endless with no results.
