Also, you can hear a popping noise every now and then from the speakers when sound is played. Raspbian continues to run, except for every USB device or the Ethernet port.\r\nI found dozens of threads for \"Failed to read reg index 0x00000114\" but they all are a year old and there the problem got fixed in April 2014 with a firmware update. Maybe this has something to do with the USB controller on the Raspberry Pi 2 specifically?\r\n\r\n- The problem does not occur when I connect the speakers directly to the headphone jack and disconnect the sound card.\r\n- The sound card is connected to a powered USB-Hub (but problem does also occur if i connect it directly to the Pi)\r\n- Raspberry receives enough power (constantly 5V)\r\n- Doesn't matter if a WiFi Stick or Ethernet cable is connected.\r\n- Tested two different USB-soundcards that are confirmed working (one from adafruit and a Creative Play sound card)\r\n\r\nI'm at a loss here. Headphone jack is working fine, but sound isn't that good.\r\n\r\nI uploaded the interesting part of the syslog to pastebin: http://pastebin.com/yn4PUUwm"}}
