8.2.6.12 sound@8 Test
The following is an example of a successful sound@8 test:
To check for audio output, you must enable loopback for the test. Type:
The sound@8 test now sends audio out to the speaker, the headphone jack, and the
audio-out jack simultaneously. The test also displays errors as the loopback signal is
not returned. These errors can be ignored.
You need to reconfigure the test arguments before performing any other tests. See
Step 3 in “Configuring OpenBoot Diagnostics” on page 8-7.
