Audio
  • Occasionally, audio cannot be played back, and no sound cards appear in /proc/asound/cards special file
Workaround:
Exercise power cycle (turn power off)
Notice:
In many cases video playback will fail if no audio is available.


3G modem
  • Occasionally, Telit 3G modem cannot detect the SIM card.
Workaround:
Istruct the modem to assume SIM card is present, i.e. similate SIM inserted, by adding to the startup script the appropriate line in function ril_initialize, prior to starting ril-daemon:
echo -en "AT#SIMDET=1\r" > /dev/ttyACM0
