Hello all, this is not really a big problem, but I see this on mythfrontend log:

2012-03-07 20:48:19.559 ALSA, Error: Setting hardware audio buffer size to 192
2012-03-07 20:48:19.559 ALSA, Error: Error opening
/proc/asound/card0/pcm3p/sub0/prealloc: Permission denied.
2012-03-07 20:48:19.559 ALSA, Error: Try to manually increase audio
buffer with: echo 192 | sudo tee
/proc/asound/card0/pcm3p/sub0/prealloc
2012-03-07 20:48:19.559 ALSA, Error: Unable to sufficiently increase
ALSA hardware buffer size - underruns are likely

Here is a complete log: http://pastebin.com/raw.php?i=v3m1rfz7

If I execute manually the command, it change the buffer value, but on
the next reboot there is the same problem.

How could I solve this problem? Is this really necessary?

Thanks and best regards.
