System Freeze / Audio Dropout Investigation:

The highest priority of this beta is investigating reports where the Ui24R temporarily becomes unresponsive during normal operation.  When this issue occurs, users may experience a 10–20 second interruption, sometimes longer where the entire system appears to stop responding.  Symptoms may include:

  • Loss of mixer control from connected devices
  • HDMI output disconnecting or displaying the Soundcraft logo while reconnecting
  • Audio playback stopping
  • Meters and all activity freezing where a ‘connecting’ message shows on the connected device
  • Network control becoming unavailable

The mixer then eventually recovers without requiring a reboot (in some cases).  Because the Ui24R hosts its own internal web server, this interruption affects both local and remote control of the mixer.  

 


Instructions:

  • Update your Ui24R to firmware version: 3.6.8341
    • Instructions on how to update your Ui24R
  • Use your Ui24R in normal day to day operation
    • The more audio channels and DSP in use, the more stress placed on the equipment the better.
  • Wait until an audio drop event occurs: 
    • DO NOT POWER CYCLE YOUR UNIT AFTER THE AUDIO EVENT.  Log files do NOT persist between power cycles.

**NEW** Log Collection:

  • Insert a USB stick into side port # 1 as shown below

 

 

  • Navigate on the web GUI to the Settings icon

 

 

  • Press the ‘Copy Logs to USB’ button.
