I enabled logging in audio_out.c I notice that the current delay start at
around 13000 and then slowly increases. 10 minutes later is is allready
around 26000.
The gap isn't that large. Sometimes it is large (6000) and then decreases
rapidly to < 200. I am not sure for what message I should look to track the
problem. However, I saw the following comment in audio_out.c:
 * - it will only be updated 2 times for the whole audio fifo size
 *   length (so the control will wait to see the feedback effect)

However, I never use my full audio fifo. I only use 15 audio frames. Is
this something which could be a problem?
