I am using Beagle Board Rev. C4 and ran omapfbplay sample application for Angstrom. The app shows video but no audio. However, the mplayer plays audio. Is it any setting on the omapfbplay application to turn it on/off?
omapfbplay does not support sound.--Wmat 20:39, 11 August 2011 (UTC)
I am using Angstrom newest version for beagle board Rev.c4. I downloaded uImage from same angstrom beagleboard.org proposed site.
I have seen in the Internet that there are a lot of discussions about how to setup the NFS server in the beagleboard and angstrom. I followed some recommendations provided by eLinux.org document file BeagleBoardFAQ#NFS. I followed procedure step by step but my NFS connection does not work.However with another system I am working on a DM355, the NFS works fine, meaning that the NFS server is setup properly on the Host PC.
It seems that the problem is that the beagleboard network connection is not initialized properly before the NFS. However USB/ETH driver is recognized (ASIX AX88772), but not mounted. Please see some portion of the trace below. Thanks.

First off, you'd get many more answers on the BeagleBoard mailing list. Second, it would appear that you're not running the services necessary for NFS on 192.168.1.31. --Wmat 23:50, 15 August 2011 (UTC)
