Increase text to speech volume
I saw some threads on the volume increase. I have done it but the volume played on the mobile is still low. I have created text to speech and increase the volume to 100% using edit audit. I have even set the audio volume at the audio bar to high. Additionally, I have optimised my volume and set the audio byte to 128. After publishing and play it using different mobiles, the volume is still low. Anyone can help me if I have missed out any step to increase it.
