Tataplay should fix the audio issue as soon as possible..I observed some channels have high volumes and some low, so in each channel need to adjust volume
Example: colors hd, Cineplex hd and mtv beats hd , I have low volume, I keep it at 18 whereas other channels like mastii, b4u music ,zee bollywood I keep the volume at 11-12 max.. similarly in max hd I am keeping at 14/15..
Another sd channel star gold thrills has higher volume as compared to any other sd and hd channels
