Hello all, I am having some errors on Nvidia ION frontend:
2011-09-18 14:07:40.924 ALSA, Error: Error opening
/proc/asound/card0/pcm3p/sub0/prealloc: Permission denied.
2011-09-18 14:07:40.924 ALSA, Error: Try to manually increase audio
buffer with: echo 128 | sudo tee
I try to increase it manually, I execute it: (I add frontend user to sudoers)
echo 128 | sudo tee /proc/asound/card0/pcm3p/sub0/prealloc
I get this on dmesg:
[35928.171738] data write error to prealloc (-16)
And there is no buffer change, it continue with same value. It must
execute with no playback, on playback there is no change.
I read that this is not necessary, I am having some playback problems
and I don't know if it is related to this.
I will appreciate any help. Thanks and best regards.
