Can I open two sound cards at the same time on an Android device?

There is an android device(android TV) connected with iPod via usb. I would like output pcm data which is from usb path to TV's speaker.

In this case, the system would create two pcm device nodes, one is for ALSA sound card(output) and the other is for usb audio(input).

Can Android handle two audio devices at the same time? In other words, does it work well if I open both pcmC0D0p and pcmC1D0c on android?

thank you.

The kernel drivers used on Android are normal Linux drivers. So if the kernel has the USB audio driver enabled, and if you actually manage to open both device nodes (the normal Android APIs do not allow to select an audio device), then you will be able to use them both.
