RE: MPD error Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout - Tim Curtis - 10-10-2021

The log entries below labeled "ALSA" indicate Linux/ALSA did not recognize any audio device. The DigiOne would normally be configured at card 0.

Code:
20211010 100203 worker: -- Audio debug
20211010 100203 worker: ALSA cards: (0:empty | 1:empty | 2:empty | 3:empty
20211010 100203 worker: MPD config: (0:Allo DigiOne | mixer:(Digital) | card:0)
20211010 100203 worker: ALSA mixer actual (Digital)
20211010 100203 worker: ALSA Digital volume set to (Invalid card number.)

When configuring a DigiOne in Audio Config its driver overlay would be added to /boot/config.txt

Code:
dtoverlay=allo-digione

When the driver is loaded by Linux during startup it attempts to find the audio device at card 0. You can look in dmesg to see if Linux successfully creates an I2S mapping for the device. The example below is for my Allo Boss2.

Code:
pi@rp2:~ $ dmesg | grep i2s
[    6.878845] asoc-audio-graph-card soc:sound: allo-cs43130 <-> fe203000.i2s mapping ok

Tim,

I have the same error I have select the right DAC in Audio Moode 7.40 and install mpd-oled (Adrian)

RPI3b/Audiophonics 9038/MPD-Oled

Thanks
Jem

RE: MPD error Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout - Tim Curtis - 10-29-2021

Start with a fresh 7.4.1 image, re-seat the board on the Pi and set "Audiophonics ES9028/9038 DAC" in Audio Config and then reboot. You should see the line below in /boot/config.txt and the command "dmesg | grep i2s" should return "...i2s mapping ok"

Code:
dtoverlay=i-sabre-q2m

If there are no hardware, media or connection issues then Linux/ALSA will configure the audio device during boot and moOde software will be able to use it.

Tim,

oke I will try this

The DAC may only work in moOde when ALSA output mode is set to "Direct (hw)"

Tim,

I can select Direct(hw) but cannot set it

how to do that?
