No Alsa/jack from zynthian image but Hifiberry Amp+ plays from hifiberry image

Building Zynthian
1

Wasted an afternoon on this one…

I had an encoder not turning but twittering, so opened up and examined.
seemed ok, closed up and everything went haywire.

Pi booted then shut down WITOHUT recording a syslog (that I could find)
I loaded the sds into a seperate machine and couldn’t find a log. . .

Assumed I’d killed something, unplugged stripboard, same problem . .
Loaded old hifiberry sds
aplay test.wav worked, so it appears the HifIFberry Amp+ is ok. (phew…)
burnt a new sds from original zynthian downloaded image . . .
upgrade_zynthian twice . . .
booted but failed on jack start up.
Could however get a ssh shell , ( and hdmi console prompt)

with image I now try aplay -l and only get null . . .

and aplay -L I get Null . . .

Have I partially killed the Amp+ or have I forgotten some aspect of the set up?

Confused of Cheshire …

I would compare the hifiberry sds and the updated zynthian one. Especially the boot directory.
Have you tried zynthian image without encoder plugged in?
Killed the zynthian process and tried aplayer?

Work today, (django . . ) and the rest of the week, A chance to clear my head and come at this one again.

You can try a Minibian image on a sep. SD. If “aplay -l” can show you some informarion about your Hifiberry you have luck…

Sorry - no more ideas yet…

It is rather hard to kill zynthian isn’t it …? :slight_smile:

root@zynthian:/zynthian# kill -9 2171

root@zynthian:/zynthian# ps -ef | grep zynthi
root 4570 1 0 19:45 ? 00:00:00 /bin/bash /zynthian/zynthian-webconf/zynthian_webconf.sh
root 4575 4570 1 19:45 ? 00:00:01 /usr/bin/python3 ./zynthian_webconf.py
root 4756 1 0 19:46 ? 00:00:00 /bin/sh /usr/bin/startx ./zynthian.sh – :0 vt3

root 4921 1084 0 19:46 pts/0 00:00:00 grep zynthi

I think it’s a corrupted sds . . I can’t edit /boot/config.txt

6

I shut it down with systemctl stop zynthian and restart with systemctl start zynthian - which is pretty clean.

7

Now that does seem a bit more mature …

Ok new image burnt but not updated . . .

zynthian stopped see above . . .

encoders unplugged.

root@zynthian:~# ps -ef | grep zynth
avahi 259 1 0 20:43 ? 00:00:00 avahi-daemon: running [zynthian.local]
root 7912 627 0 21:38 pts/0 00:00:00 grep zynth
root@zynthian:~# aplay -l
aplay: device_list:268: no soundcards found…
root@zynthian:~# aplay -L
null
Discard all samples (playback) or generate zero samples (capture)
root@zynthian:~#

I’m burning a hifiberry raspbian -lite image to see how that works . . .

Nope it’s the settings in /boot/config.txt . . . .

It needs to be . . . .
> # Audio Device Driver:

dtoverlay=hifiberry-amp

& comment the

dtoverlay=hifiberry-dacplus

(don’t no how to display code in this board …)

root@zynthian:~# aplay -l

**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_amp], device 0: HifiBerry AMP HiFi tas5713-hifi-0
Subdevices: 0/1
Subdevice #0: subdevice #0

Does the web-conf config this if the card is changed …?

Ok testing that the hifiberry Amp+ works . . .

so over an ssh -X root@192.168.1.12 ( the address of My particular zynthian )

aplay /zynthian/zynthian-data/soundfonts/sfz/Drums/SalamanderDrumkit/OH/cowbell_MP_3 .wav

aplay: main:722: audio open error: Device or resource busy

So… we do have alsa because aplay -l sees the card.

But jack has grabbed the card to do good stuff so we want to turn that off. . .

qjackctl & ( this works cos you did the -X on ssh )

and stop jack . . . . on the interface …

But still resource busy . . .

Lets see what is using the snd . . .
lsof | grep snd

(lsof lists open files you might well need apt-get install lsof )
( | is a pipe the output of the first command is stuffed straight into the next command)
( which i grep… grep searches for text in this case the letters snd )

and gives …

jackd 383 root mem CHR 116,16 8604 /dev/snd/pcmC0D0p
jackd 383 root 10u CHR 116,0 0t0 8603 /dev/snd/controlC0
jackd 383 root 12u CHR 116,16 0t0 8604 /dev/snd/pcmC0D0p

jackd is still runinng . .

So lets be nasty . . .

killall -9 jackd

aplay /zynthian/zynthian-data/soundfonts/sfz/Drums/SalamanderDrumkit/OH/cowbell_MP_3 .wav

JUST THE RIGHT AMOUNT OF COWBELL !!!

SUCCESS !!

Congrats on getting it working! With jack running, does mpg123 play?

11

Could you post the output of “amixer scontrols”?

12

Yep . . .
mpg123 /zynthian/zynthian-data/audio/test.mp3

Is our African Gentleman.

amixer scontrols
Simple mixer control ‘Master’,0
Simple mixer control ‘Channels’,0

I have subsequently discovered he is a Cuban gentleman.
Apologies.

His name is “Papito Angarica” from the “Povoloti” district of La Habana. The recording is one of the “Abbilona” series, dedicated to the Orisha “Oya” :wink:
