Re: Disable touch function?

Thanks. This works fine. I had hoped that it might be possible to disable under program control without needing a reboot, but nevertheless this is useful.

Re: NFS automount /etc/fstab with Jessie

This is great. I've been trying to get auto mount of my nfs share to work since moving to Jesse, and it always hung because the wireless network was not fully up when it was called.
adding noauto,x-systemd.automount to the fstab entry sorted it.
Many thanks

Re: Rassberry Pi and Jack audio

THis is an old thread, but I wonder if there is anyone out there who can help with adding mmap support to the driver for the IQAudiO Pi-DAC+ card which connects via the i2s bus.
I would like to use this with Sonic PI, but it won't connect via jackd because it doesn't support mmap.

Ok re not using PWM
I wish I hadn't done an rpi-update. It kills Sonic Pi on the Pi 2. Sam Aaron is aware of this but doesn't yet know why. Can anyone give me the git hash for the firmware in the latest Raspian release on 31/1/2015 so that I can downgrade to it?
