Troubleshooting Without Diagnostics

✎If you set digital as your Output Mode, the internal speaker and external analog speakers will no longer output audio until you switch back to an auto-sense or analog mode.

If you set analog as your Output Mode, external digital speakers will not function until you change the output mode back to an auto-sense or digital mode.

See Appendix D, “Setting up Analog/Digital Audio Output” for additional information.
