Lisa Compact 39
Note that for proper operation of the fallback to card, the preset URL must point directly to an audio
stream. If the preset URL actually points to a playlist that contains several audio stream URLs, the Lisa
will try the next URL in the playlist in case of problems with the stream. However, if the internet
connection itself is failing, this will not help.
Take the following steps to set up the Lisa for fallback:
·
Create a playlist with the name '1.pls' (without the quotes), according to the Requirements for playlists
on the card . For testing purposes, it is recommended to use the Streamit Card and Scheduler Toolkit
to create the playlist.
·
Copy the playlist and the tracks that it uses onto the SD Card, according to the Requirements for
audio tracks on the card .
·
Insert the SD card into the Lisa
·
Power cycle the Lisa (power off, power on)
8.3 Test the fallback setup
Testing the fallback setup is straightforward and is done as follows:
·
Make the Lisa play an audio stream from internet
Note that for proper operation of the fallback to card, the preset URL must point directly to an audio
stream. If the preset URL actually points to a playlist that contains several audio stream URLs, the Lisa
will try the next URL in the playlist in case of problems with the stream. However, if the internet
connection itself is failing, this will not help.
·
Remove the network cable from the Lisa
·
Wait 1-2 minutes and verify that the Lisa plays from the card in fallback mode (see Verify if the Lisa
plays from the SD card in fallback mode ). Fallback may start sooner, but depending on the bit rate of
the stream that was playing, the audio buffer may last longer and actual start of fallback may take time
(see
The audio buffer for details).
It may take some time before the Lisa switches back to the stream when the internet connection is
restored, because the Lisa finishes the track it is playing before returning to the stream
8.4 Verify if the Lisa plays from the SD card in fallback mode
You can verify that the Lisa plays from the SD card in fallback mode by the following:
·
After fading out, the Lisa starts playing again, even though the network cable is removed
·
The 'Audio' LED lights up orange (see LED status information )
·
If monitoring the Lisa on the platform is enabled, '(FB)' is shown in front of the playlist and track
number information.
