I am a little unsure about this patch. Let me explain...

Here you /decide/ by user it ought to use ALSA for volume. This has a
considerable risk break someone's application which uses PulseAudio to
manage it and expect it to be used as the default setting.

This is not a BSP thing but a application layer/product option.

What others think?

The .desktop fix is not a BSP one, please work on a proper fix in OE-Core.
