I've been using this firmware as per texy's instructions at: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=45&t=48967
I've got got his screen working fine but I have an issue with a usb sound card that I'm using - it stutters and sounds get very distorted at times.
Is there a way that I can combine the sound fixes in the official firmware with your firmware or any other possible fix to this?
Do you have sound problems without the FBTFT driver loaded?
If No, try to use DMA with FBTFT (lowers the CPU load). See: https://github.com/notro/fbtft/wiki#install
If Yes, try the vanilla firmware that the latest FBTFT release is based on, to see if the problem exists there
I'm planning to make a new release when 3.10.y becomes the main kernel: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=29&t=55711
I tried with dma loaded and the same problem exists - Looking at htop output it's not high cpu that's causing the issue - although a lower cpu load will be useful for the next stage of the project so thanks for pointing that out.
The second command just error-ed.
Is there something that I can do abut this or is it just a case of being patient and waiting for the next release?
