[How To] CD playback

[felix]

Hi Francesco

Apologies - the disc does spin (I can hear it) but nothing happens within moode.

ls -l /dev/sr* delivers:
brw-rw---- 1 root cdrom 11, 0 Oct 18 07:48 /dev/sr0

sudo eject succeeds in ejecting the CD

Aha, you have some Linux command-line skills.

Here's some nitty gritty details. Yours should be substantially similar in name, location, permissions, etc.

Preliminaries

1. The install script places two files in the directory /etc/systemd/system

Example from my player

Code:

pi@m82x64b:~ $ ls -l /etc/systemd/system/*audiocd*.service
-rw-r--r-- 1 root root 138 Oct 15 22:38 /etc/systemd/system/addaudiocd.service
-rw-r--r-- 1 root root 137 Oct 15 22:38 /etc/systemd/system/remaudiocd.service

The script also places two files in the directory /usr/local/bin 

Code:

pi@m82x64b:~ $ ls -l /usr/local/bin/*audiocd*
-rwxr-xr-x 1 root root 503 Oct 15 22:38 /usr/local/bin/addaudiocd.sh
-rwxr-xr-x 1 root root 341 Oct 15 22:38 /usr/local/bin/remaudiocd.sh

When the USB CD drive is plugged in

The syslog (/var/log/syslog) or dmesg output should show it has been recognized. Here is the relevant dmesg output when I plugged in the LG drive mentioned in the github README.

Code:

[  124.040149] usb 1-1.3: new high-speed USB device number 5 using xhci_hcd
[  124.145609] usb 1-1.3: New USB device found, idVendor=0e8d, idProduct=1887, bcdDevice= 0.00
[  124.145627] usb 1-1.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3

[  125.185580] scsi 0:0:0:0: CD-ROM            HL-DT-ST DVDRAM GP65NB60  PF00 PQ: 0 ANSI: 0
[  125.202724] scsi 0:0:0:0: Attached scsi generic sg0 type 5
[  125.223416] sr 0:0:0:0: Power-on or device reset occurred
[  125.232137] sr 0:0:0:0: [sr0] scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray
[  125.232152] cdrom: Uniform CD-ROM driver Revision: 3.20
[  125.238856] sr 0:0:0:0: Attached scsi CD-ROM sr0

Note that it is identified as sr0 and includes "cdda" (audio CD) and "tray" among its attributes.

Note also, the cdrom driver is invoked. When an audio CD is inserted in the drive, a new device link should appear. For my system

Code:

pi@m82x64b:~ $ ls -l /dev/cdrom
lrwxrwxrwx 1 root root 3 Oct 18 10:10 /dev/cdrom -> sr0

As you can see, it is a symlink to the correct drive.

When an audio CD is inserted in the drive

The addaudiocd.service should be invoked. Here is a snippet from my system log (/var/log/syslog)

Code:

Oct 18 10:10:25 m82x64b systemd[1]: /etc/systemd/system/addaudiocd.service:1: Unknown section 'UNIT'. Ignoring.
Oct 18 10:10:25 m82x64b systemd[1]: Started addaudiocd.service.
Oct 18 10:10:25 m82x64b systemd[1]: addaudiocd.service: Succeeded.

[Probably should fix the harmless UNIT issue but as the syslog shows, it's ignored.]

MPD proceeds to index the tracks on the audio CD.

Code:

pi@m82x64b:~ $ mpc playlist
cdda:///1
cdda:///2
cdda:///3
cdda:///4
cdda:///5
cdda:///6
cdda:///7
cdda:///8
cdda:///9
cdda:///10
cdda:///11
cdda:///12
cdda:///13
cdda:///14
cdda:///15
cdda:///16
cdda:///17
cdda:///18

and that's what appears on the moOdeUI display.

Hello Kent

First - thank you for bearing with me.

Second, though I really have no Linux command line skills. I'm just doing what Fransesco told me to do!. 

However, I can try to do the same from your kind email, but with limited success as follows:

1. /etc/ststemd/system directory

As you can see I cannot find an 'audiocd' file. Looking in the directory I can see 'addaudiocd.service'$\r.

But I do not understand what that means. I also don't know how to neatly embed the code like you do, so forgive a copy and paste readout below: 

pi@moode:~ $ ls -l /etc/systemd/system/*audiocd*.service
ls: cannot access '/etc/systemd/system/*audiocd*.service': No such file or directory

2. /usr/local/bin directory

Here I can find the two folders:

pi@moode:/usr/local/bin $ ls -l /usr/local/bin/*audiocd*
-rwxr-xr-x 1 root root 503 Oct 17 18:33 '/usr/local/bin/addaudiocd.sh'$'\r'
-rwxr-xr-x 1 root root 341 Oct 17 18:33 '/usr/local/bin/remaudiocd.sh'$'\r'

3. dmesg output

The full output is long. I really *hope* is about to appear in a neat code box. If it doesn't I'll edit. *edit* is in attached doc. *edit* can't do that either hopefully the below is enough

But the bit at the end reads:

Hello Felix, hello Kent,
@TheOldPresbyope 
the problem is, probably due to the test on the old /var/www/command/moode.php that does not exists anymore.

@felix 

try to do that:

Code:

nano /home/pi/moOdeCDPlay-master/install.sh

moving with the arrow keys, add an "#" at  the begin of each of the following lines:

Code:

if [ ! -f /var/www/command/moode.php ]; then
   echo
   echo "I'm sorry, Dave, I'm afraid I can't do that."
   echo "In case you didn't notice, this doesn't look like a moOde installatio>
   exit 1
fi

 
in order to get:

Code:

#if [ ! -f /var/www/command/moode.php ]; then
#    echo
#    echo "I'm sorry, Dave, I'm afraid I can't do that."
#    echo "In case you didn't notice, this doesn't look like a moOde installati>
#    exit 1
#fi

Then save the file (Ctrl "o" and Enter) and exit (Ctrl "x")
At this point repeat the installation:

Code:

/bin/bash /home/pi/moOdeCDPlay-master/install.sh

Reboot:

Code:

sudo reboot

 try and let's know.

Good luck and best regards,
Francesco

Oh, dear, those weird filenames suggest to me that the moOdeCDPlay-master.zip file was unzipped on some other host running a different O/S and then its contents copied over to the moOde player (or the github repo was cloned to the other host and then the individual files were copied over).

Based on their sizes and locations, they appear to be the correct files, just with corrupted filenames (so, for example, your 'addaudiocd.service'&'\r' file is my addaudiocd.service file).

I overlooked another critical file which gets copied over to its proper directory by the install script

Code:

pi@m82x64b:~ $ ls -l /etc/udev/rules.d/*srX.rules
-rw-r--r-- 1 root root 259 Oct 18 12:38 /etc/udev/rules.d/99-srX.rules

My guess is that on your system this file too has a weird name along the lines of '99-srX.rules'&'\r'

If it weren't for the file renaming, I think you'd be playing tracks.

So, what to do? The cleanest approach would be to delete all the offending files, reboot, and repeat the install instructions in the GitHub repo README. This includes downloading a fresh copy of the zip file and unzipping it directly on the moOde player.

The following commands should succeed in removing all the weirdly named files. These are to be entered from the command line of the moOde player and the asterisks are required. 

Code:

sudo rm /etc/systemd/system/*audiocd.service*
sudo rm /usr/local/bin/*audiocd.sh*
sudo rm /etc/udev/rules.d/*99-srX.rules*

 
NOTE: I have (finally!) updated the github repo to fix the install script so commenting out the lines containing the if statement is not required to install to a moOde 8.x player. As well, the update has fixed the harmless 'unknown' UNIT section message logged to syslog. Hence, I recommend downloading the moOdeCDPlay-master.zip file again.

Regards,
Kent

PS - a knowledgeable Linux user likely would just rename the offending files. Safer to assume the files are in fact not to be trusted.

[felix]

Kent - ah. Yes. That is exactly what I did. I can’t ‘see’ the pi on my network and I don’t know how to unzip in terminal. So I unzipped on my pc and transferred the unzipped folder using FileZilla.

Francesco - shall I try what Kent suggests and then turn to yours given that sounds like a smoking gun?

How best to unzip though, subtitles for the hard of thinking please…..?

Again, both - I cannot believe the amount of time you’re putting into a stranger’s (non real world) issues. Thank you.

[TheOldPresbyope]

@felix

(Slightly different from my README) You can download the zip file and unzip it, all from the command line in moOde.

So, once you've SSH'ed to the moOde player and deleted the misnamed files enter the following commands (If you don't want to type lines in, you can copy and paste one line at a time or all of them at once from the code box to the command line, hitting return after each paste. The comment lines are no-ops.)

Code:

# first, make sure we're in the home directory
cd

# download the current github master
wget https://github.com/TheOldPresbyope/moOdeCDPlay/archive/refs/heads/master.zip

# unzip it and change to the subdirectory moOdeCDPlay-master containing the desired files
unzip master.zip
cd moOdeCDPlay-master

# execute the install script
/bin/bash install.sh

# following the Done prompt, reboot

ETA - this works as-is on moOde 8.2.1.

Regards,
Kent

[felix]

I AM PLAYING TRACKS
Thank you both so much for your patience and your help.
The kindness of strangers....
I really don't know what to say. Other than to thank you. And to hope that some day something I can do can reciprocate.

[fdealexa]

Hi Felix,
glad you are happy.
Best regards and thanks,
Francesco

@felix

Really glad to hear you succeeded. Like Tim’s signature line says, “enjoy the music!”

…and think about ripping those CDs to FLAC files

PS- how far is “NW London” from somewhere I can still remember having been, like Speakers Corner in Hyde Park?
