Subject[Cs-dev] Question about new entry for dmix on realtimelinux.xml
Hi,
Francois Pinto, during his translation to french, has asked me:

> in overview/realtimelinux.xml: in line 101 and 116 should we read
> 'buffer_size 12288' instead of 12384? (12288 is 4096*3). In line 117
> should we read 48000/16000 instead of 16000/48000? 

Is that correct?

Cheers,
Andrés
