6. If the USB cable and the HDMI or DP cable are connected from monitor to the
computer, two audio paths named DELL S2422HZ or S2722DZ and Echo
Cancelling Speakerphone (S2422HZ or S2722DZ) from the monitor will
show in the Sound dialog box. The S2422HZ or S2722DZ monitor would show
options for two audio paths supported in the monitor.
• Echo Cancelling Speakerphone (S2422HZ or S2722DZ) audio path is
where audio streams through USB. This is either through USB-C to USB-C
cable or USB-A to USB-C cable. As the microphone path streams from
monitor back to computer through USB, this selection is required for VolP/
UC conference applications. Audio Recording and Playback works in this
selection.
• DELL S2422HZ or S2722DZ audio path is where audio streams through
HDMI/DP/DP alternate mode. Microphone is not supported in this selection.
This selection is suitable for Audio Playback only.
Audio Playback performance is same for both audio path options. Under normal
Playback with USB-C to USB-C/USB-A to USB-C and/or for UC conference
applications, it is recommended to select the default Echo Cancelling
Speakerphone (S2422HZ or S2722DZ) audio path.
