Does audio/x-gsm work on CDMA devices?

[sbeck45]

I wrote a small test program that captures x-gsm audio on my AT&T 9000. The audio is written to a file on the device. Then I can play this audio from the file on the phone. This program works perfectly on the simulator and on the AT&T 9000.

In case it matters, the program is compiled using the 4.6.0 SDK in Eclipse 3.5.

When I try to run this program on a CDMA 9630, I can run the program to capture audio and write the file. But when I try to play the file back, all I hear is static. I copied the file from the 9630 to the 9000 and tried to play it. All I hear is static. Then I captured audio on the 9000 and copied the file to the 9630, and played it - static!

So it seems that record and play of x-gsm does not work on the CDMA 9630.

Has anyone every captured and/or played x-gsm on a CDMA device?
