After flashing the firmware on your Vivo PD1924F, are you facing issues with no sound during calls or while playing media? This problem often occurs when the audio partitions are skipped during flashing, or an incompatible build is used. In this guide, we’ll help you fix the sound issue step-by-step with the official stock ROM.

Common Reasons for Sound Problems After Flash

  • Corrupt or missing audio firmware partition
  • Incompatible or incorrect region firmware
  • Disabled audio codec drivers during flashing
  • Incomplete flashing (missing rawprogram.xml or patch.xml)

Requirements to Fix Audio Issue

  • Vivo PD1924F Official Firmware
  • QFIL Flash Tool (QPST)
  • Qualcomm USB Drivers

Steps to Re-Flash and Restore Sound Function

  1. Install Qualcomm USB Drivers on your PC.
  2. Extract the downloaded firmware using 7-Zip or WinRAR.
  3. Open QFIL Tool and select Flat Build.
  4. Click "Browse" and load prog_emmc_firehose_xxxx.mbn from the firmware folder.
  5. Click Load XML and select both rawprogram.xml and patch.xml.
  6. Connect the Vivo PD1924F in EDL mode using the test point method.
  7. Click Download in QFIL to start the flashing.

Note:

If the sound issue still persists after flashing, perform a factory reset from recovery mode and ensure no third-party audio app is conflicting with system audio drivers.
