Using ASRC from within Android

Hello,

We are trying to use the ASRC for clock domain synchronization within a daemon in the Android system. This is a similar use-case as in this post: i.MX6 ASRC audio support

Here we see that a plugin for ALSA can be used to configure the ASRC. However, on Android we only have tinyALSA, which I don't think supports these features. Is there some way this can be integrated with tinyALSA? Or perhaps there could be a setup with ioctl to the ASRC to configure it from there?

Best Regards,

Joe Pentland

Hi,Joseph,

ALSA in android does't use alsa config to control sound card like in linux. It's controls are all in ALSA HAL (tinyalsa._hal.c). So if you want to expend functions, you should add code in ALSA HAL .

ALSA in android also uses alsa-lib , So your expened function should also be based on API in alsa-lib.
