Sound and screen resolution

Sat Jul 14, 2012 8:59 am

Hi,
I'm trialing a raspberry pi for 8 weeks and I've stumbled across two problems, nothing major, but a bit annoying.

First of all, I can't seem to get any sound from the RPi. I've tried in the built in media player and in scratch. I've seen problems with HDMI audio from RPi on the internet., but I can't get it through the headphone jack either.

Secondly, I'm running on a high resolution tv, and as my nearest seat is about 2 metres away, and the tv is small, I can't read anything on screen, I've set it to a lower one for now but I don't like it because it only uses part of my tv. Here's my config.txt file:

Code: Select all

sdtv_mode=2
hdmi_group=2
hdmi_mode=8
overscan_left=20
overscan_right=12
overscan_top=10
overscan_bottom=10

I notice that your hdmi_group=2. This is using the DVI modes rather than the HDMI modes - have you tried other modes from hdmi_group=1?

Also this might explain some of your sound issues as sound is not sent over HDMI if you select the DVI modes for the video.

If you just want bigger text, I'd suggest reducing the framebuffer size.

E.g. remove everything else and try:
frambuffer_width=1024
framebuffer_heght=576

I had this problem, no sound with the LX music player - it seems that debian wasn't packaged with codecs for mp3 etc. you also need to insert an instruction to turn the soundcard on - I found this really useful.

also this gets the codecs
sudo apt-get install xmms2-plugin-all (credit to mortimer)

i am currently using vlc player which should play video and music but its struggling with .mod files - any ideas????
