stuttering audio on raspi2 with 7" touch display and speaker - klegg - 2015-10-19

1. Problem
  • what: The image stream looks smooth but the sound is shortly interrupted every 2 seconds.
  • when: watching Live TV streams or Video Addon streams (I tried ARD Mediacenter, arte.tv or zdf mediacenter).
  • full log: http://pastebin.com/Rdt2LA5Q
2. Configuration
2.1. Hardware
  • Raspberry Pi 2B
  • official 7" TFT Touch Display connected via DSI (not SPI, thanks popcornmix)
  • X-mini speaker connected via raspi 3.5 mm audio jack
  • wired LAN connection to Fritzbox 7390 (-> 25Mbit)
  • Power (5V/2A) to Display mini usb and via GPIO to the RPi
Attention: I do not use a TV nor a remote control nor other devices.

2.2. Software
OSMC (Version 2015.09-2) updated 18-10-2015 (Kodi 15.2-RC2)
  • Confluence
  • IPTV Simple Client
  • mpeg2 codec
  • VC1 codec
2.3 Installation
osmc auto install program for windows writes the osmc image for 'Raspberry Pi 2' version '2015.09-2' to 'SD' card.

What does
Quote:official 7" TFT Touch Display connected via SPI
mean? Are you talking about this which connects by DSI, not SPI.
Or do you mean an SPI display from some other source?

you are write:
I talk about the Raspberry Pi 7" Touchscreen Display
I substituted SPI with DSI.
Thanks

I have the exact same problem with the official display.
the same on OpenElec and OSMC.
in raspbian video and audio are fine but the video playback resolution does not fit the display.

Currently only the Milhouse nightly builds produce correct LCD resolution and have proper touchscreen support.

problem solved!

1. go to system and change "settings level" to Advanced.
2. go to Videos > Acceleration.
turn on "Allow Hardware Acceleration - OMXPlayer."

that solved my problem. audio and video are running smooth.
