Subject: HuskyLens V2 - I2C playMusic() returns "No ACK" / Fail during Object Tracking (ESP32)

Hi DFRobot Team and Community,

 I am working on a project using the HuskyLens V2 connected to an ESP32
 (Waveshare General Driver for Robots board) via I2C.
 My goal is to track an object using the ALGORITHM_OBJECT_TRACKING and play a
 sound file (01.wav) from the SD card when the object is detected.

 Setup:
  * Board: ESP32-WROOM-32UE (Waveshare General Driver for Robots)
  * Core: Arduino ESP32 Core v2.0.11 (via PlatformIO espressif32 @ 6.4.0)
  * Communication: I2C (SDA=32, SCL=33), 100kHz clock.
  * Library: DFRobot_HuskylensV2 (latest version)
  * HuskyLens Firmware: Latest V0.5.1a (checked via update tool)
  * SD Card: FAT32, contains 01.wav (PCM 16kHz Mono) in root directory.

 The Problem:
 The object tracking works perfectly. I can receive coordinates and control my
 servos.
 However, when I try to call huskylens.playMusic("01.wav", 100) while tracking
 is active, the function always returns false.

 If I debug the return value, it indicates a failure to communicate (No ACK
 received from HuskyLens for the command).

 Code Snippet:

  void loop() {
      huskylens.getResult(TRACKING_ALGO);
      
      if (huskylens.available(TRACKING_ALGO)) {
          // ... tracking logic ...
          
          // Try to play sound on detection
          if (!wasObjectDetected) {
               bool success = huskylens.playMusic("01.wav", 100); 
               if (success) Serial.println("ACK Received");
               else Serial.println("No ACK / Failed"); // <--- This always 
  happens
          }
      }
  }

 Troubleshooting steps taken:
  1. Isolated Test: I created a minimal sketch doing ONLY playMusic() in a loop
     (no tracking algorithm active). Result: Still fails (No ACK).
  2. File Format: Tried 01.mp3 (44.1kHz) and 01.wav (16kHz PCM). Same result.
  3. Bus Reset: Added delays and Wire resets. No change.
  4. Wiring: Checked SDA/SCL. Tracking works fine, so I2C connection is good.
  5. Protocol: Verified HuskyLens is set to "I2C" mode in settings.

 Question:
 Does HuskyLens V2 support receiving the ACTION_PLAY_MUSIC (0x2A) command via
 I2C while an algorithm is running?
 Is there a specific timing requirement or a known bug where the audio command
 is ignored on the I2C bus?

 Any help or workaround would be appreciated!

 Thanks.
