Official moOde 6.6.0 support thread

[lurkio]

The log message below suggests a hardware, DAC-to-Pi connection, or PSU issue because it's showing no device name after card 0 (0: ). It should show something like 0: Piano or something like that.

Code:

20200712 114502 worker: Device raw: (0:|1:empty|i2s:Allo Piano 2.1 Hi-Fi DAC)

The device name is registered by linux in the card id.

Code:

cat /proc/asound/card0/id

You could also check the boot log for errors loading the Piano I2S driver

Code:

dmesg |grep allo-piano

Example of successful load of Katana I2S driver

Code:

pi@rp3:~ $ dmesg |grep allo-katana
[    9.801003] asoc-audio-graph-card soc:sound: allo-katana-codec.1-0030 <-> 3f203000.i2s mapping ok

Hi Tim
I ran - dmesg |grep allo-piano  

and got this which doesn't look good

pi@moode:~ $ dmesg |grep allo-piano
[    7.100864] snd-allo-piano-dac-plus socound: ASoC: Neither/both codec name/of_node are set for PianoDACPlus

[    7.100948] snd-allo-piano-dac-plus: probe of socound failed with error -22

and the cat /proc/asound/card0/id returns

cat: /proc/asound/card0/id: No such file or directory

I think @DRONE7 has a Piano 2.1 rig. Maybe he can provide some info.

So after further fiddling I can get it to work using the "Allo Piano hifi dac" setting but this means I have lost my sub

so maybe there is just something wrong with the Piano 2.1 setting file ?

Lx

You have to download and install the Piano 2.1 DSP firmware files from Allo's site. They can't be bundled in a distribution like moOde because of restrictive licensing.

sorry Tim it doesn't work - I used the instructions (below) that you gave me some time ago, maybe something has changed ?

cd ~
wget https://github.com/allocom/piano-firmwar...master.zip
sudo unzip -q master.zip 
sudo rm ./master.zip
sudo cp -r ./piano-firmware-master/lib/firmware/allo /lib/firmware
sudo rm -rf ./piano-firmware-master

I used to be able to use the Piano 2.1 Dac settings for stereo even if I hadn't downloaded the DSP files, now I can't use it at all
It still fails with
" Failed to open "ALSA default" (alsa); Failed to open ALSA device "hw:0,0": No such file or directory"

@hestehandler

I don't know the root cause of your issue, but I can say that the messages which mpd throws for .m4a files (as reported in one of your posts) are benign and do not reflect some underlying problem.They are a indirect consequence of the decoder path which mpd takes to deal with the ALAC content in the MPEG4 container. It's just information the ffmpeg codec thinks you should know.

As a confirmatory test I downloaded a collection of .flac, .mp3, and .m4a demo files from Hyperion to a NAS and added the NAS as a new music source to moOde 6.6.0 running the 64-bit kernel on an RPi3B+. All the tracks load, the album count is correct [1], and the .m4a tracks play just as well as their .mp3 and .flac versions do.

Thus, neither .m4a material nor the 64-bit kernel per se seem to be causing a problem.

Kent

[1] the mpd stats and the thumbnail generator stats are not identical because of my directory structure. I was lazy and threw the Hyperion tracks from three different albums with metadata to match into one "Hyperion album" directory.

I've run into an issue in the same neighborhood as @hestehandler. Similar setup -- 4B 4gb, with a usb dac. When I started it up in 32 bit, .21xxx MPD, it created the database quickly (aroun 15-20 mins for 4085 albums), and worked fine. I then switched to the .22 MPD and it commenced to rebuild the llibrary. After over an hour, in had not finished. I rebooted and checked the file directory listing and it was around 25% of the total. Wiping the Tag cache and regenerating the library stalled again. I switched back to .21xx MPD, the library scan once again went quickly to completion. 

Just to be sure i attempted again to use .22xx, but the library regeneration failed in the same manner. The move back to .21xx succeded again as well. Plays very nicely.

happy to search logs and run diagnostics.

I should have mentioned I tried both mpd 0.21.24 (Default) and the mpd 0.22~git (Test) over the 64-bit kernel without seeing a difference with my small test library. Will check again with default 32-bit kernel.

Perhaps if you turn on mpd debugging (must manually edit the /etc/mpd.config file to set log_level "verbose" in the MPD Config menu) you could gather useful data related to the difference you see.

Regards,
Kent

PS - it should be noted that at this moment in time, the two versions of mpd are practically identical because 0.21.24 was released very recently. I was doing this test because I wanted to confirm mpd was working over the 64-bit version kernel and not because I believed there was a substantial difference in mpd versions.

[Tim Curtis]

Note: there is an option in MPD Config to set logging level. Its the last option on the screen :-)

I actually compiled 0.22 MPD shortly before releasing 6.6.0 so there should be a greater number of commits to it since 0.21.24. The commit I compiled is 4d88bddfe223776d893f86beb33e62994acc848e

[mangkook]

tried 6.6.0 updated from 6.5.2 audio glitch once in a while, same as 6.5x. already tried change governor to performance and usb dac fix. glitch while playing local file and spotify too.

back to 6.4.2. last moode that work fine with my pi zero W and my topping D10 usb dac

is it the limit of cpu / ram?

[DRONE7]

@DRONE7
@Tim Curtis

USB DAC (tried 2 of) and when trying to select in MPD Config   I get Device type=> Nothing Selected.
How odd... not even Onboard Audio.

Curious. The Official Touchscreen display doesn't use the HDMI interface. Do you have another local display plugged in?

As it happens, I just installed a fresh moOde 6.6.0 on an RPi3B+ with official touchscreen display and USB DAC this morning. It's working fine.

Code:

pi@moodeLD:~ $ cat /proc/asound/cards
0 [Headphones     ]: bcm2835_headphonbcm2835 Headphones - bcm2835 Headphones
                     bcm2835 Headphones

                     Creative Bluetooth Audio W2 at usb-3f980000.usb-1.1.2, full speed

Regards,
Kent

I got same results with my Pi-3 Touch screen rig + a USB DAC whose ALSA name is "DAC"

Code:

pi@rp5:~ $ cat /proc/asound/card0/id
Headphones
pi@rp5:~ $ cat /proc/asound/card1/id

cat: /proc/asound/card2/id: No such file or directory
pi@rp5:~ $ cat /proc/asound/card3/id
cat: /proc/asound/card3/id: No such file or directory

This is now way curious...
Rebooting overnight and nothing is recognised today.. no onboard, no USB, and nothing plays. An error message saying no hw:0 yet a usb dac is connected.

I tried enabling/disabling the HDMI port to see if that made any difference..it didn't,
then running your suggested

Code:

cat /proc/asound/cards

0,1,2,3 found nothing yet the USB DAC is connected.

Noting your comment about card numbering I found another DAC in the junk box (just a cheap soundcard type) and tried that with no result either.
Then I tried with both USB DACs connected and low and behold I now have them both recognised...

Code:

pi@touch:~ $ cat /proc/asound/card0/id

Most probably a hardware problem then...I am wondering if the on-board audio is broken and  as it is not showing as card0 (Headphones) and this breaks the configuration ?? Note that the Perreaux Audiant 80i is called 'On-board audio device' in the above A U D I O P A R A M E T E R S

Odd...I went to see if onboard was turned off in /boot/config.txt and it is an empty file ?? Is this normal ?? or has something changed in how moode sets boot parameters. ?
Maybe I will just reflash an earlier version as this setup has worked in the past (sat idle in a cupboard for a few months) and see if the problem is there too.

[Tim Curtis]

For sure an empty config.txt will cause lots of wreckage cos its a critical file. Are you sure your dog hasn't been exploring your cupboards for something to chew on ;-)

Re-image!

[Skip Pack]

I turned on verbose mpd logging and created a monster file, 90% of which reflected being caught in a loop. All .flac files added showing a single line log entry. Every other file type threw a bunch of extra entries.  The first one here reflects what happened on each .wma file:
