Re: U2715H, AC511 Soundbar, no sound on reboot
* Click my name and private message me both of the monitor service tag numbers
* The usage of connecting the AC511 USB Soundbar to a dock was never validated by Dell. The AC511 USB Soundbar User's Guide page 7 shows it connecting directly to the monitor USB downstream port. The monitor USB upstream cable is then connected directly to the PC USB port. Setup as the User's Guide dictates and retest
