Hi,
I used omap3530 with tps65930 to develop a voip project, and my project is based on a open source
project "linphone", and linphone uses ALSA audio framework. when I used the version of 2.6.28 linux
kernel, audio is ok, I can capture and playback at the same time, but when I ported the project to
PSP-03.00.01.06(2.6.32 ), I only can capture or playback at a time, can't capture and playback at the
same time. I checked sound driver, I found that this version of sound driver has been changed to use
omap3530 internal audio buffer(McBSP2: 4096 bytes), on the function of "omap_mcbsp_dai_startup()", this
buffer will be all alocated to tx or rx, so this driver didn't consider the case of audio rx and tx at
the same time. Could anyone please tell me how to modify this driver? thanks
Best regards
