Very first impressions: Since I don't want to compile a new kernel (>12h on the R-Pi) I used that image: http://blog.georgmill.de/wp-content/uploads/2014/04/kernelAndFirmware_wolfson_rt.tar.bz2 On a Linuxbox I unzipped it and wrote the image to a 4Gb card using an ordinary cheap card reader: dd if=2014-01-07-wheezy-raspbianW.img of=/dev/sdd "of" is the device of the card reader got by "fdisk -l" (Don't ask me about doing this on a WinBox. Poor girl here.) Plugged into a R-Pi with the "Wolfson" in place this image booted without any errors. It will run "raspi-config" first where you have to do some boring config tasks (lang. etc.). OT here. Next I plugged in an antenna/preamp into the red plug and started this modified bash script as root (!): #!/bin/bash # Record from onboard Line Input to AP # input PGA gain amixer -Dhw:0 cset name='IN3L Volume' 4 # (mod by Laura) amixer -Dhw:0 cset name='IN3R Volume' 4 # (mod by Laura) # better THD in normal mode vs lower noise floor in high performance amixer -Dhw:0 cset name='IN3 High Performance Switch' on amixer -Dhw:0 cset name='IN3L Digital Volume' 128 amixer -Dhw:0 cset name='IN3R Digital Volume' 128 amixer -Dhw:0 cset name='LHPF1 Input 1' IN3L amixer -Dhw:0 cset name='LHPF2 Input 1' IN3R amixer -Dhw:0 cset name='LHPF1 Mode' High-pass amixer -Dhw:0 cset name='LHPF2 Mode' High-pass amixer -Dhw:0 cset name='AIF1TX1 Input 1' LHPF1 amixer -Dhw:0 cset name='AIF1TX1 Input 1 Volume' 32 amixer -Dhw:0 cset name='AIF1TX2 Input 1' LHPF2 amixer -Dhw:0 cset name='AIF1TX2 Input 1 Volume' 32 # The following command should be used to test (mod by Laura) arecord -Dhw:0 -r 192000 -c 2 -f S16_LE test.wav Looking into "test.wav" with "Baudline" all the usual suspects from 10-96 kc are present. The "Wolfson" appears quiet and flat. At ~53 and ~63kc I'm observing some signals from the 2nd Nyquist domain. The experts will know which. Boring: running "arecord" I got many overruns. Overclocking (900 Mhz) did not cure this. Guess it's due to a slow SD card. Next step: streaming. Hope that "flac" will work. ? Laura Sent from my HapPyPhone
