Play 2 sounds on Storm 9520, why it's not possible ???

login1505 · ‎12-15-2009

Hi,

I develop a game, I need 2 players - one for background music, and another one for effects.

I found that it's not possible to make 2 players and play sounds at the same time on CDMA devices, but my device IS NOT CDMA. Anyway second player stops first player. Why? It's not a CDMA device, my device is 9520 Storm2.

And second question, is there any way to check is device support 2 or more players or support only one player?

RIM Developers support, please help, how to develop cool games if we can't make one ot the most important thing - cool music in games.

Thanks all!

It is a CDMA-capable device. It cannot play two streams concurrently. There's a knowledge base article about this, but I can't seem to find it...

He said it is not a CDMA device.

Correct me if I'm wrong, but all Storm2 BlackBerrys can operate on US CDMA networks. That makes them CDMA-capable, requiring a different chip (Qualcomm) that results in this weird limitation. It does not matter whether the device is connected to a CDMA network or not.

I agree with what you are saying, I'm just restating what the author of this thread stated. Storm2 has a 9520 (the one he is talking about) which is a supposedly non-CDMA phone, the 9550 is the CDMA Storm2.

I had a similar issue trying to help someone working on recoding audio and the 9530 (CDMA) and 9500 (non-CDMA) and the audio encoding only worked on the 9500 but not the 9530 even though they have the same chips.

I got my information from http://www.blackberry.com (UK) "Compare Devices" feature. It lists 9520 as CDMA-capable: the device supports Dual-band 800/1900 MHz CDMA2000 1X Ev-DO networks.

That's what I expected. Do you happen to know why something like 2 audio streams/Players are not possible on CDMA devices? I tried to get more information and could not find anything of use.

I finally located the KB article I was referring to: http://www.blackberry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/1089414/Suppor...

Good work, it's unfortunate but unavoidable.

Now I have the urge to write a player that can play 2 or more audio streams on CDMA devices.

You might be able to write a software audio mixer to do this, but that's a highly nontrivial job.
