MPD Error - joecurtis - 01-08-2024

I have been running an RPI 2B for a number of years, outputting via the on board connector to a powered speaker or by a dongle to a bluetooth speaker without any problems.

I have recently added an IQaudIO Pi-digiamp+ to the PI to output to a pair of hifi speakers but am getting the error 'Failed to open "ALSA Default (ALSA)" etc. when I try to play a file. I have tried reflashing the micro ssd card and also installing on a Pi 3B but with the same result.

It appears that the system is not seeing the IOaudIO card and the appears to be born out by the attached log.

I would be grateful for any pointers for incorrect setup parameters or ways to test the IOaudIO card before I take it up with the suppliers.

RE: MPD Error - Nutul - 01-08-2024

You power the board, which in turn powers the Pi, right?
From the logs it's not clear to me why ALSA has no clue about the card.
It looks like somewhere the card is seen, and also MPD expects it on its port 0.

Do you have any additional hardware attached, that might conflict?

Or I better stop conjecturing, and let's wait for somebody more skilled than I am... ;-)

RE: MPD Error - steve4star - 01-08-2024

Have you disabled the Pi Audio in config.txt ?

I am not using the DigiAmp, but for the DAC+ I had to disable the Pi headphone.

Which overlay are you using ?

Config.txt is a managed file. the dtoverlay and other settings are determined by what is set in the Config Screens.

If you have to manually edit config.txt audio settings there is some breakage.

I thought that particular board hasn't been available since IQaudIO went out of business quite a few years ago?
it's possible the Linux kernel driver doesn't work with it anymore.

I think I still have one of the boards lying around. If I can find it I'll run some tests.

Haven't the Raspberry Pi folks taken over the IQAudiO line and are selling this item as the Raspberry Pi DigiAMP+ board?

quote from their docs:

If you need to configure Raspberry Pi OS yourself, perhaps if you’re running a headless system of your own and don’t have the option of control via the GUI, you will need to make your Raspberry Pi audio board the primary audio device in Raspberry Pi OS, disabling the Raspberry Pi’s on-board audio device. This is done by editing the file. Using a Terminal session connected to your Raspberry Pi via SSH, run the following command to edit the file:[/url]

Code:
/boot/firmware/config.txt

RE: MPD Error - Tim Curtis - 01-08-2024

@Nutul I2S audio devices are all configured via Audio Config. The should never be a need to manually edit the boot files :-0

I did manage to find my old 2B + IQaudIO Pi-DigiAmp+
A quick test and no issues whatsoever.

Is your board an IQaudIO board or the new one from Raspberry Pi?
