GeeXboX Advanced Configuration – Audio Configuration

 

Setting up your audio output device …

XBMC system settings menu allow you to configure a lot of different audio settings, as shown on the picture above:

Several audio settings can be configured through this dedicated menu, such as:

  • Audio output device
  • Speaker configuration (number of channels)
  • Boost volume level
  • AC3/DTS pass-through capability (if your end receiver supports so).

Forcing audio card to be used …

While it tends to be less and less true, some PCs still have multiple audio cards (e.g. on-board one + additional PCIe one).

If that’s the case, GeeXboX allows you selecting which one has to be used.

In order to do so, connect to your box and update the /etc/audio file accordingly:

# Soundcard to use by name (e.g. “SB”) or by ID (0 for first card, 1 for second, …)
ALSA_CARD=”0″

and replace the ALSA_CARD variable by the desired one.

Forcing audio output mode …

If for any reason, the XBMC system audio settings panel is not enough for you to configure your audio output mode, it is also possible to manually force it by hand.

In order to do so, connect to your box and update the /etc/audio file accordingly:

# Output mode ( analog/digital/hdmi )
# digital is used for SPDIF/IEC958 output
SOUNDCARD_MODE=”analog”

This allows you to fine tune your audio output mode by choosing between Analog, Digital/SPDIF and Digital/HDMI outputs.

Forcing number of audio channels …

If for any reason, the XBMC system audio settings panel is not enough for you to configure your audio channels number, it is also possible to manually force it by hand.

In order to do so, connect to your box and update the /etc/audio file accordingly:

# Playback channels
# 2 – Stereo
# 4 – Surround
# 6 – Full 5.1
# note: in SPDIF and hardware AC3 decoder mode this option is ignored.
CHANNELS=”2″
