[mythtv-users] Error: Setting hardware audio buffer size to 6016

[Brent Bolin]

I have just compiled from source to get mythzoneminder to work with
the correct colors

git clone -b fixes/0.24 git://github.com/MythTV/mythtv.git

Mythtv is working fine but I'm seeing an error message that I've never
seen before -


2011-05-20 20:51:04.218 AO: Opening audio device 'default:CARD=NVidia'

2011-05-20 20:51:04.281 ALSA, Error: Unable to sufficiently increase

Even when I try to do this as root the value doesn't change -


root at brent:/proc/asound/card0/pcm0p/sub0# echo "6016" > prealloc
root at brent:/proc/asound/card0/pcm0p/sub0# cat prealloc
