hello nanomescher,
I have a slot-in drive with no physical eject button.
Every time I want to eject the CD, I have to press View Settings–>Plugins–>Installed Plugins–>Settings of Nanosound CD–>Eject Button.
It would be very nice if you could add a separate eject button directly in the browse menu under NanoSound CD. With an additional eject button, I would listen to audio CDs more often than I do now.
thank you nanomesher for the great cd plugin.
I concur, it’s a great plugin but I also use a slot-in drive, so an easily accessible eject button would be very welcome!
Hello Nanomesher Team,
I need help 
I got a SATA drive and installed the Nanosound CD plug in, however It doesn’t seem to be working,
it does allow me to eject a CD through Volumio, however it does not ready the contents of the CD at all I did test the drive on my Windows 10 machine and it seems to be working 100%
I am currently using a Raspberry Pi 4 - 8GB with a 128GB memory card.
Thanks in advance 
Hi,
I am using a IQaudio Dac Plus with Volumio 2.882 and the plugin installed. It has been working previously very well but since I
changed the mixer type to none the cd plays but no sound comes out. I tried auto config audio and
it still didnt work. I then changed the mixer back to software and did the auto config again
and it still did not work.
the results from /data/nanosound_cd/asound.conf can be found below
defaults.pcm.card 2
defaults.ctl.card 2
defaults.pcm.rate_converter “speexrate_best”
pcm_slave.x4 {
pcm “hw:2,0”
rate 176400
}
pcm_slave.x2 {
pcm “hw:2,0”
rate 88200
}
pcm.rate_convertx4 {
type rate
slave x4
Any help would be appreciated as it was a great plugin.
Can you please paste the content of /etc/asound.conf ?
thx
Its empty.
Change you please change it to </data/nanosound_cd/asound.conf>
or just run
echo “</data/nanosound_cd/asound.conf>” | sudo tee -a /etc/asound.conf
thanks
It could be a power issue. Do you hear it spins? thanks
Hi there, I hear it spin, and I see the light flash, but then it comes to a stop, when I click on Nanosound CD in Volumio, I hear no activity from the drive.
Thank you. works now.

Bug description
The plugin can be installed manually or by using the pre configured image without a problem. I can see the additional nav menu entry in the Volumio UI. CDs get read and I can see the track list. The CD and any track can be played and I can see the progress.
The plugin messed up the ALSA config. Running the CLI player list for the sound cards results in the following error output:
$ aplay -l

So it boils down to an invalid config from the plugin not being able to pick up the active, external DAC.
There are a couple of things I noticed, aside from a CD playing without audio output:
</data/nanosound_cd/asound.conf> lines in /etc/asound.conf. I notices in the install log (+ details) in the plugins screen that you check for duplicate plugins. You might want to do the same for pre-existing config lines. The line echo "</data/nanosound_cd/asound.conf>" | sudo tee -a /etc/asound.conf in your install.sh Bash Script is the source.dpkg-query -W -f='${Status}\n' vlc 2>/dev/null | grep -c "installed" returns 1 for installed and 0 for not installed.Additional note: The instructions on the Nanomesher homepage are missing an important part regarding the REST API and the start/ stop scripts to auto run or stop playing when a CD is inserted/ injected:
# /etc/udev/rules.d/99-local.rules
KERNEL=="sr[0-9]", ACTION=="change", ENV{DISK_EJECT_REQUEST}=="1", RUN+="/home/volumio/stopcd.sh &"
You can look up the original instructions by sideshowbob in this thread.
Further, the GitHub repository that is linked in the instructions post tells about issue tracking. In fact it’s linking to open pull requests. You might want to change the wording there @nanomesher.
@nanomesher please take a look at the previous post, as I forgot to mention you for a notification.
Hey @AionDemon
The cat commands just print the file contents to stdout (which probably just is the console you opened via PuTTY. aplay -l just lists all playback hardware devices.
The actual definition is what you configure inside /data/nanosound_cd/asound.conf.
Note that speexrate_best defines that resampling will be used. It might use a lot more CPU there, especially when for e.g. 88200 is used, when the actual rate is 96000Hz. Would be nice to have/ find some default CD sampling rates and setting up the conf according to that.
I have Volumio running on an old MacMini 2009.
I installed the plugin via Method 2 – Run the installation script.
Finally let volumio restart and enable the plugin.
But the CD is not read or displayed. Ejecting the CD works.
Then verify that installation is ok, I check below services are running:
systemctl status nanosoundcd_web
systemctl status nanosoundcd_progressweb
And below the result. There is one error message. Anyone have any idea if this can be solved?

Hi,
may i ask if there are plans on bringing NanoSound CD to volumio 3? I have seen that there are commits related to volumio 3 on github . I tried the install script, but after the install the plugin is not shown in the volumio gui. One problem i have noticed during the install was that vlc could not be installed.
vlc : Depends: vlc-plugin-base (= 3.0.12-0+deb10u1+rpt3) but it is not going to be installed
Depends: vlc-plugin-video-output (= 3.0.12-0+deb10u1+rpt3) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Thanks a lot and kind regards
Hello,
I am having a issue with a slot load cd/dvd player that I hope you may be able to resolve. Using the Nanosound CD, Volumio 2.873, and an LG tray load cd/dvd (USB 2) things are working well.
When I switch to the slot load player, NO NAME BRAND, Two usb connectors, one USB 3 the other USB 2. The system doesn’t seem to know what to do with it. It will eject the disk thankfully but beyond that it just kinda grunts and groans. This cd player works well on a Windows base pc.
I have a NANOSOUND ONE, Pi 4 4gB, 256GB USB stick, Argon Power Supply.
Any thoughts?
I am confused about the software. What does the NANSOUND ONE plugin do?
Ripping a cd to 4x upsampling but in playback it shows 44.1kHz and it appears that Volumio is doing the playback. Does NANOSOUND CD do playback from the USB ?
Thanks
hello.
Currently I am using volumio 3.324. I can’t get the nano sound cd to read the CD no matter what I do. Can you just help me?
@nanomesher
Nanosound CD has not been ported to Volumio 3 yet.
thanks you! so sad
this way you can use cd
