Audio latency on Kindle Fire and Nook Tablet

I am trying to deploy my app to the Kindle Fire and Nook Tablet. Everything is going pretty well except that there is a long audio latency period. In some cases as long as several seconds between the time the code is suppose to play the sound and the user actually hears it. The same code on the iPad works fine. I am using audio.loadsound and audio.play to play the sound. From what I have read this is the preferred method. I have tried 128bit and 96Bit sound files but it makes no difference. I have tried loading the sound files from the root directory instead of a sub directory but that also does not seem to make a difference.

This latency is so bad I am very concerned about submitting to the Amazon or Nook marketplaces. Any ideas on how to correct this?

I actually have a very similar problem on Nook and Kindle. My Gun App has similar complaints, but only on the Nook Color. There is only a very slight delay on the Nook Tablet and Kindle.

The only way I know how to prevent it, is loading the sounds with a stream, and playing the audio. Stream’s are faster then audio.loadSound, but it doesn’t allow you as many features.

I’m really surprised this has not been fixed. It has been a know bug since the kindle fire build was added. Using the audio stream is a hack not a real solution for a fix. [import]uid: 7177 topic_id: 22716 reply_id: 90704[/import]

I’ve noticed the lag is much worse with the newer builds I have played with…2012.773 and 2012.776.

A while back I was working on an ebook done with the comics api, and the lag wasnt noticeable on the nook.

I’ve reverted back to build 714 to ship on the nook. And it just got approved yesterday on B&N. [import]uid: 9070 topic_id: 22716 reply_id: 98985[/import]

There are numerous posts with replies from Ansca that basically says its a problem with Android’s sound implementation. Nothing can be done about it.

I have indeed seen the posts and the Ansca comment.

I was simply reporting my own personal observation that the impact is seemed lesser to me with 2012.714.

YMMV.
