Test tone will not play after initial setup

Does the audio file exist in the audio library?

Under some circumstances, the installation does not create the sound file in the audio library for the test tone. If this is the problem, you will not see file 999999_000.wav in the directory /var/snd.

If the file does not exist, check that you have write access to the directory and run in a console:
rdgen -t 10 -l 16 /var/snd/999999_000.wav

Does Rivendell see my sound card?

Log into RDAdmin > Manage Host, then select your computer > Edit > Audio Resources, then scroll down to the heading AUDIO ADAPTERS to see if Rivendell found your sound card.

If not check to see if /etc/asound.conf is setup properly.

Typical asound.conf setup with single stereo input and single stereo output. For more of the same cards uncomment the lines for the cards you want to active in Rivendell by removing the # from the front of the lines for the complete section.

#/etc/asound.conf

## First sound card with one stereo input and one output
pcm.rd0 {
    type hw
    card 0
}
ctl.rd0 {
    type hw
    card 0
}
