After a recent Windows update, there is no longer any audio output from the device.
Within windows, i can mute/unmute the audio, however the physical keyboard button shows muted audio (LED is on), and audio playback doesn't work regardless of what windows displays. I have managed to get audio output through bluetooth, however the internal speakers and audio jack outputs do not function. When connected to external speakers(audio jack) i can hear crackling noises during system startup (As if the output was muting/unmuting multiple times).
The system diagnostic tools detect no problems with audio output, i have only managed to get this error code on HP Startup Manager when checking for hardware issues:
Audio[P] Failed PU748X-99L9RH9-MFPW3F-21C703 Audio
To resolve this problem i have tried the following(without any success):
-system rollback to pre-update state / rolling back audio drivers
- updating all drivers manually / through HP utillities
-updating the BIOS
-a clean install of windows + updating drivers / BIOS
- trying out other fixes mentioned on this forum
I would greatly appreciate help in further troubleshooting of this issue
