Audio device playback/ recording are not showing in the sound menu. even speaker icon also not showing. Realtek Audio disappeared from my device manager, i install audio drivers again but still not appear. Firstly this error comes after install update 1709.
Restart your computer and check if the problem resolve, If not than try following steps
Check USB connection and make sure it’s correct if the connection are not an issue then connect external device to another computer to see the problem
Check DMA or PIO settings
DMA is turned on auto during install for DVD, CD-ROM external device. Due to system error, PIO or DMA setting may configured incorrectly.
Open Control Panel> click on System and Security> click Device Manager. Open “IDE ATA/ATAPI controllers”> right click on device which is causing the issue> click on Properties
Right click on the device name and click Update Driver Software. Follow the process to update it.
Now, it is working fine!!!
