Still I'm unhappy: The 4713 needs to have a signal on its DCLK and FS pins to be able to switch into I2S mode at all. CLK and FS are not allowed to stop, otherwise the 4713 will leave digital mode.
They way it is working right now is, that I have to start mplayer and then initialize the radio IC. As soon as I pause, stop, skip to the next track the radio IC will leave digital mode and needs to be initialized again. This behavious is supposed to be normal. The datasheet says:
Is there a way to keep them supplied by configuring the Pi the right way? Do I have to use another driver? (Right now I could only making it work with latest raspian 2014-09-09 image and tjaekel's RCAplus configuration)Ensure that DCLK and DFS are already supplied.
This is what my /etc/modules looks like:
I also thought about using some kind of internal mixer and having a silence played back all the time and use mplayer to overlay it. Tried it with two mplayer instances but — of course — soundcard is already in use...
Code: Select all
##snd-bcm2835 snd_soc_core snd_soc_bcm2708_i2s bcm2708_dmaengine snd_soc_pcm1794a snd_soc_rpi_dac
Do you guys have any idea how to handle this?
Thanks in advance,
