I am running ubuntu 13.10 on my BBB and I want to get an audio signal from the I2S pins on the P9 header. I am also trying to use a LCD cape on the BBB.
I get an audio signal without the display connected. I am able to play mp3 files using mplayer and alsa.
However, when I connect the display, aplay -l reports
aplay: device_list:268: no soundcards found…
I have tried the options in the uEnv.txt files,
but that does not work.
How can I get an audio output and also use the LCD cape at the same time?
This has to be one line, as you are redefining the "optargs" variable,
before it has a chance to disable the other two..
Do i change the line to
Probably the 2nd, not sure if order actually matters.
I use the later, enable last and it works as expected.
I seem to be making a mistake here.
I don’t have an audio cape, which i have been trying to enable in the uEnv.txt.
I am using a DAC connected to the I2S pins on the P9 header. This works when there is no display, but doesn’t work when there is a display connected.
