After installation of a HiFiBerry DAC, omxplayer does not output sound through the DAC.
Recently, I was using omxplayer to play audio out of the headphone jack. Recognizing I needed higher quality audio for my application, I sprung for a HiFiBerry DAC2 Pro XLR. As per the installation instructions, I did the following:
I edited `/boot/config.txt` by commenting out:
```
#dtparam=audio=on
```
In the same boot config file, I configured the device tree overlay file:
```
# for hifiberry DAC2 PRO
dtoverlay=hifiberry-dacplus
```
I creating /etc/asound.conf:
```
pcm.!default {
type hw card 0
}
ctl.!default {
type hw card 0
}
```
And then to test, I installed mplayer and tested it successfully.
```
mplayer stereo-test.mp3
```
But when I ran omxplayer on the same file, I did not get output to the HiFiBerry DAC.
How do I have to configure the audio system so omxplayer outputs to the DAC as well, or get more info about what is really going on?
