My Lumia 730 speaker sound is not clear after reinstall of OS

I installed the Windows 10 update on my Lumia 730 but I didn't liked it so I used the Windows Device Recovery tool to get back to Windows 8.1 but firmware is bumped to 02040.00021.15235.53005 from originally 02040.00021.15063.02004 and now whenever I play music on my phone's loud speaker the sound deteriorates after 20/30 volume level. I think the firmware has to do something with it so how can I install the 02040.00021.15063.02004 firmware again? Or any other suggestion to fix my sound problem.

improper installations from WDRT can have some bugs but this doesn't seems likely form it. anyways try hard reset and reach back if the problem still persists .

make sure all the apps under store are updated

I performed a hard reset on my phone and all apps are up-to-date but still the problem persists. I just want to downgrade the firmware hoping that will solve the problem.
