Gang, So I am designing a A2DP sink with an AVRCP source. ~~~ Or is there some other way of handling this? Thanks, Gordon -- J.

This email sent to site_archiver@lists.apple.com I am looking to get information on the best quality of audio output I can get from Bluetooth. I know the codec has a lot to do with it, but I am looking even further than that. Volume control? In general all digital volume controls will reduce the resolution of each sample so I am wondering... do I signal the A2DP source with AVRCP to make the volume = 100% will that result in the best data available at my A2DP sink? Digital volume controls in the source will basically multiply the float32 sample with the digital volume percent to create the new sample. But since we get fixed point samples at the endpoint this basically means we loose resolution if the volume control is set to something other than 100%. I can control the actual volume in the analog domain which will result in the best support of the digital samples.
