Audio Testing on the XO
This page contains the results of testing audio on the XO. If you're looking for the XO Test plans, they're up at this page.
Current Status
- Audio out works only through the headphones [466038]
Audio under OLPC's latest build
- The OLPC build doesn't include pulseaudio, but they are using ALSA under 2.5.25.
- They use the following udev rules:
- /etc/udev/rules.d/40-alsa.rules
# do not edit this file, it will be overwritten on update KERNEL=="controlC[0-9]*", NAME="snd/%k" KERNEL=="hwC[D0-9]*", NAME="snd/%k" KERNEL=="pcmC[D0-9cp]*", NAME="snd/%k" KERNEL=="midiC[D0-9]*", NAME="snd/%k" KERNEL=="timer", NAME="snd/%k" KERNEL=="seq", NAME="snd/%k" KERNEL=="mixer0", SYMLINK+="mixer" KERNEL=="dsp0", SYMLINK+="dsp" KERNEL=="audio0", SYMLINK+="audio"
- /etc/udev/rules.d/90-alsa.rules
SUBSYSTEM=="sound", KERNEL=="controlC*", RUN+="/sbin/salsa" SUBSYSTEM=="sound", KERNEL=="pcm*", RUN+="/sbin/salsa"
Audio under Fedora 10 Snapshot 2
- We use the following udev rules:
- /etc/udev/rules.d/90-alsa.rules
ACTION=="add", SUBSYSTEM=="sound", KERNEL=="controlC*", \ RUN+="/sbin/alsactl -E ALSA_CONFIG_PATH=/etc/alsa/alsactl.conf --initfile=/lib/alsa/init/00main restore /dev/$name" ACTION=="remove", SUBSYSTEM=="sound", KERNEL=="controlC*", \ RUN+="/sbin/alsactl -E ALSA_CONFIG_PATH=/etc/alsa/alsactl.conf store /dev/$name"
