8.2.5 -> 8.3.2: lost audio device

[Busybox]

I just updated in-place from 8.2.5 (which was working fine) to 8.3.2, and now I have no audio. When I attempt to play a radio station, the following briefly flashes on the screen:

Code:

MPD error
Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": No such file or directory

Not sure what to do about this./var/log/mpd/log contains multiple copies of the following:

Code:

ALSA lib pcm_hw.c:1829:(_snd_pcm_hw_open) Invalid value for card
Apr 26 13:54 : exception: Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": No such file or directory
Apr 26 13:54 : exception: Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": No such file or directory
Apr 26 13:55 : player: played "http://158.69.74.203:80/"

I did make a backup of my configuration before I did the update. Should I restore my backup? Burn a new SD card from scratch? My audio device appears to be correct in the configuration screen though. Any suggestions would be appreciated.

Regards,

- Steve

It seems that when moode probes for the configured audio device, it's not finding it but it did in v8.2.5. Did something change about the probe method or driver?

Did you, by any chance, reboot the device after the upgrade?

[Tim Curtis]

The log entries below indicate a problem with the file /boot/config.txt

Code:

20230426 152622 worker: WARNING: Boot config restored
20230426 152622 worker: WARNING: Restart required

The /boot/config.txt file looks like below on a fresh image.

Code:

pi@sig:~ $ cat /boot/config.txt
[cm4]
otg_mode=1

[pi4]
hdmi_force_hotplug:0=1
hdmi_force_hotplug:1=1

[all]
disable_splash=1
disable_overscan=1
hdmi_drive=2
hdmi_blanking=1
hdmi_force_edid_audio=1
hdmi_force_hotplug=1
hdmi_group=0
dtparam=i2c_arm=on
dtparam=i2s=on
dtparam=audio=on
#dtoverlay=disable-wifi
#dtoverlay=disable-bt

If yours is empty or otherwise looks corrupted then edit it and replace the contents with the above, then reboot.

Code:

sudo nano /boot/config.txt

Ctrl-x y to save

sudo reboot

You will prolly need to reset Audio Config to HDMI 1, reboot and then set it to your preferred audio device.

[Busybox]

Well, my /boot/config.txt file was empty! So I copied in the proper text and rebooted. After doing so and rebooting, when I run 'moodectl -l' I get the messages shown below. The system comes up without any complaints and looks like it's playing, but I get no audio. I can't seem to set my audio device to HDMI- the only option I have in the 'audio device" drop-down is "I2S audio device." I assume I'll have to edit some file(s) manually but I have no idea where to look. I did a recursive grep in several places but nothing relevant turned up. Please advise.

Thanks,

- Steve

1) ALSA seems not happy with the mixer

2) it looks like you have the HDMI port disabled (I don't know if this is relevant only for VIDEO out, though). If you use it as audio out, I remember somewhere having read that the audio is enabled ONLY if the video is; so, worth a check.

3) your sound levels seem to be 0 (zero, not 0dB)

Have you tried changing (and then reverting, eventually) some audio parameters? Just to see if the defaults, for some reason, are incompatible with your actual setup.

I'd first try the volume type => Software, then back => Fixed (0 dB). Maybe a reboot between the changes is necessary, cannot tell for sure, but it isn't hard to find out.

Hope this helps a little more.

I had this too. (After in-place upgrade to 8.3.2)    (I do not need support thankyou)
Upgrade proceeded as expected and I played music for hours. (I also changed * below, but I don't this this is relevant.)
Shutdown fine, started today and same symptom as Mr. Busybox reports above: "MPD error Failed to open "ALSA Default" (alsa); Failed to open ALSA device "_audioout": No such file or directory".
After hunting around I saw there was an extra option for my DAC in the list under "Output device" under "Audio":
- Pi HDMI 1
- ADI-2 DAC         (my DAC)
- ADI-2 DAC         (identical entry)

I changed "ADI-2 DAC" to "ADI-2 DAC" and all is fine.

Immediately afterwards, there are again only two entries in the list:

- Pi HDMI 1
- ADI-2 DAC

*yesterday I changed "UPnP Client for MPD" from "UPnP-A/V" to "OpenHome", and all worked fine. Today, upon "ALSA" error, I tried switching back to "UPnP-A/V" but this had no effect.

15 minutes later - I have tried restarting moOde, and all is still fine, with only two entries in the list.

Things are mostly working now.

Makes sense- I had the HDMI port shut off. So I did the following:

Enabled HDMI. Set I2S audio device to "none". Reboot
Now HDMI appears as an audio output device option. Selected it. Set volume control to "software" instead of "0 dB." Reboot.
Changed the audio device back to my original selection (Audiophonics ES9028/9038 DAC (Pre 2019)). Reboot.
Set the volume and audio now plays!
Disabled HDMI and set volume back to fixed 0 dB. Reboot.
System comes up and audio plays.

However, all the radio stations I added before the upgrade have gone missing. But I can track those down and add them again.

Thanks for all the help!
