LOLA: Low Latency Audio Visual Streaming System
Appendix E – Audio Card internal Mixer settings
LOLA usually adopt RME audio cards for audio in/out functions. In order to work correctly, these audio
cards must be setup in the correct configuration to ensure LOLA gets the correct audio input channels, and
also can output the sound from the remote host correctly.
You should at first display the audio card routing matrix (see fig. 17 and 18). The top row displays the
available input channels. This information is useful to set appropriately the AudioInputOffset parameter. In
both examples, to use AN1 and AN2 analog channels the AudioInputOffset must be set to 0; to use the
ADAT A1...A8 channels, the AudioInputOffset must be set to 8 in the Fig 17 example, and to 4 in the Fig 18
one.
