25. Dezember 2018 at 19:41 #42939
I bought the 7″ Touch Display Bundle with the config from the subject. After booting it finds my squeezebox server running on my Synology NAS — but: I have no sound at all.
I have configured ‚IQaudioO Pi-DAC+ Pro‘ via WebInterface of m2p, disabled-in-build-audio, enabled I2S-MMAP, rebooted (several times, several combinations), but still no sound.
Squeezelite is not running, while autostart is enabled. When I start manually, i get the following error:
[18:36:04.898989] test_open:384 playback open error: No such file or directory
[18:36:04.899229] output_init_common:382 unable to open output device
I have added ‚-o hw:CARD=IQaudIODAC -V Digital -Q‘ to advanced options like I read in other threads, but this does not help.
Looks to me that some configuration/Kernel module is missing?!? Is the HW of the card too new? Do I need a newer beta verison of M2P? How to debug this? My Linux times have been 10 years ago, but could be re-animated with some help.;-)

Ok, installed putty. Something more I can provide for debugging? The green LED on the
PI-DAC-PRO is shining.
When I ssh to the pi, I get the following:

aplay: device_list:270: no soundcards found…

[18:36:04.898989] test_open:384 playback open error: No such file or directory: tells you that Squeezelite have found your soundcard but it can’t find the „driver“ in any file or directory!
lsmod | grep snd shows all soundcards and their options. lsmod: snd_soc_iqaudio_dac 16384 0 confirms you’re soundcard.
1. In the Raspberry Settings tap have you selected your soundcard ?? (if not select it and hit save)
2. Check: Audioplayer/Mediaplayer Squeezelite & Airplay…/Edit Advanced Options/ Have you tried all the iqaudio „drivers“ in there??

thanks for your help. I double-checked that I have selected the soundcard in the Raspberry Settings. The settings are aligned with the IQAudiO settings automagically.
In Audioplayer/Mediaplayer Squeezelite & Airplay…/Edit Advanced Options/ I can not select any IQAudiO soundcard, only ‚equal – equal‘ and ‚plugequal – Equalizer for plughw:0,0,
Does this help to debug?

I had a similar problem with my Audiophonics card I solved my problem with an kernel and package update:
Raspberry settings/Kernel and Package Updates and Upgrades.
Hope that helps, also try remove your soundcard and boot up pi once with out it.

Just reading the trouble-shooting section in
Running dmesg has the following errors on the snd card:

But googling for the errors did not give me a helping hint so far.28. Dezember 2018 at 16:44 #42964
Hmmm when I google pcm512x: probe of 1-004c failed with error -121. I find this: pcm512x They are talking about a dobble i2c. I tried to find your + pro card at iQaudio but I did not find your card. Try to disable I2S-MMAP in the settings tab and reboot28. Dezember 2018 at 17:24 #42965
The card is the following:
I set ‚I2S Enable I2S-MMAP (Mixerdevice for Soundcards)‘ to disabled… Same result.
If I have some time left I will make a backup image and try if Volumio/RUne whatever will work. In principle the card should work from what I have read googling around.28. Dezember 2018 at 19:27 #42966
And yet another test after flashing volumio:

[ 10.709166] pcm512x: probe of 1-004c failed with error -121
Same error…. Ok, the basic settings are quite the same in /boot/config.txt f.i. (after configuring via Web UI)30. Dezember 2018 at 8:38 #42971
Sounds like this could be a hardware problem either on pi or on your soundcard.
I’m sure that you have dobb. checked /boot/config.txt that you have only one entry of: dtoverlay=iqaudio-dacplus
Well Im out of suggestions for you to try now, maybe someone from Max2play can be of better help, good luck!!
