I am running a compiled version of the kernel (I needed radio capability eventually, it is not currently plugged in)
uname -a gives me: Linux beaglebone 3.14.19-ti-r27 #1 SMP PREEMPT Thu Oct 2 10:30:30 CDT 2014 armv7l GNU/Linux I have a 4 port 2.0 hub attached to the USB port. It has: usb keyboard usb sound card **** List of PLAYBACK Hardware Devices **** card 0: Set [C-Media USB Headphone Set], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0 I use the network adapter to connect to my mac. I use a console to start playback of a file alsaplayer ~/.Test.wav when I run alsaplayer to play a wave file or mp3 files, it executes normally (I assume) - I see messages on the console when packets play without a lot of additional messages. However, the USB keyboard is sub-responsive on the and keys bounce while sound is playing. Is this normal? Does the sound playback max out the USB so the keyboard stops working? If I run the spectrum example in the qt 5.3.2 examples/multimedia/spectrum directory, the graphics screen flashes between graphics and console and I see lots of status debugging messages. Message similar to: Engine::Initialize frequenciesList (8000, 11025, 22050, 44100, 48000) Engine::initialize channelsList(1, 2, 4, 6, 8) .... Anyone know how to turn them off? Did I compile the qt 5.3.2 libraries incorrectly so they dump debug messages?
