Newbie Issue w/ I2S Card(s)

[eea123]

I'm on my second unsuccessful attempt to get an I2S unit going with a Model 2B Pi. I am able to run Rune on the unit with headphone outs but couldn't get my first soldered I2S card to work and now a second GPIO pinned board. I've changed back and forth between HiFi Berry DAC and Analog Out (Current Setting with Headphone to RCA). Everything else is working like a charm, just would like to step up the audio a notch.

Hi eea123,
This setup will work fine, but the solution depends on the image which you are using. Could you post your debug or at least the first 30 lines or so from the debug screen.

Below is the following from a PuTTY session. I thought I had edited this on the SD card from the PC, but it does look like it is still REM'd out (#'d out "?"). I have some old basic DOS editing experience, but this is pretty much new turf.

Hi eea123,
I still can't see exactly which version of rune you are using. To help, I really need to see a copy of the first 30 lines or so which are shown in the normal user interface when you select the Debug menu.

Hi eea123,
OK, fine. You are using a relatively old version of the software but it will work with the HiFiBerry. Easiest way to get it working is to plug the SD-card into your PC. You may get some messages about reformatting, don't do it - just click them away. A part of the SD-card is accessible via the PC and within Linux. You see this automatically when you open the SD-card with explorer on the PC. Now you need to uncomment (remove the # symbol from the first position of a line) one line which switches the HiFiBerry on. The file you need to modify is called config.txt you can change it with any file editor like notepad. The line you are looking to uncomment is #dtoverlay=hifiberry-dac or #dtoverlay=hifiberry-dacplus, depending on the HiFiBerry model which you are using. When you are finished just plug the SD-card back into the Pi and restart. Look here for more information about doing this: http://www.runeaudio.com/documentation/ ... put-boards

You could also decide to move on to a later version of Rune, you can download that version from here: runeaudio-0-4-beta-for-raspberry-pi2-3-t4434.html#p19960 Setup is then easier, you select the Audio card in the Settings menu.

I went back to editing from PuTTY and the following line is active in config.txt.

# Uncomment one of these lines to enable an audio interface
dtoverlay=hifiberry-dac
#dtoverlay=hifiberry-dacplus
#dtoverlay=hifiberry-digi
#dtoverlay=hifiberry-amp
#dtoverlay=iqaudio-dac
#dtoverlay=iqaudio-dacplus

Are you sure I don't need to un-remark any of the following?

#dtparam=i2c_arm=on
#dtparam=i2c_vc=on
#dtparam=i2s=on
#dtparam=spi=on
#dtparam=act_led_trigger=mmc


I also confirmed that from the RuneAudio MPD menu, "HiFiBerry (I2S)" already shows as an option, it also says "(works on the fly)" on this version. It was this way when I installed the first and second I2S cards without any luck.

Maybe I'll try DAC+ next?

Got it going. Almost bought a new Pi, but rebooted with HiFi DAC+ and it took off. I also turned off the software volume control since it said that it provided better audio.
