mpdPup - Simplified MPD Music Server/Jukebox - v0.9.3

[michele_p]

Idolse,

even if I unplug the device the 96khz play is not possible.
When switching from a 44 to a 96khz tune no sound to the speakers and display of W4S show “44khz

[ldolse]

@michele_p, it sounds like a hardware/firmware issue to me with the audio_gd. The spec page claims it is supported, but I wouldn't put a lot of faith in the spec page. I found numerous Internet threads that indicate the chipset it uses does not properly implement USB Class II audio, and that it's broken on Linux. I saw one thread indicating that the 3.2 kernel should work, but upgrading to the latest kernel is low on my list of priorities at the moment. It actually sounds like you're lucky 44Khz is working based on some of the threads I saw.

Idolse,

I completely agree with you regarding the “reality

Hi Idolse,

I am still not able to mount to my NAS. I have deleted the .2fs file, this brings up the graphic interface on ssh so I can configure the settings.

I use a synology DS411+II nas with DSM 4.1. I have probably not made the right setting on the NAS, I hope you can help me with this.
I have done this:
-made a user: alix
-gave alix read and write access to the music folder.
-the nas has two volumes
-in mpdpup I put in alix as user

See attached screendump for the settings.

What an I doing wrong?

Kind regards,

[ldolse]

I suspect you're using the wrong information for the Share/Folder, but that's just a guess. Using a non-asciii password can also cause problems, but that looks fine in your screenshot.

The easiest way to see your shares is to look at the File Station application in the Synology web interface. I have one volume on my Synology, called 'DiskStation'. My Shares are under that volume, Music, Movies, etc. So my share name is 'Music', and I specify a subfolder under that - e.g. 'Library'.

Are you sure Volume2 is actually the name of your share? I'm not sure which Synology window you have open in the screenshot that says Volume2, but I'm pretty sure that's a partition and not a Share.

Hi Idolse,

Thanks! That did the trick, I did not need to fill in volume2.
It is playing now. I will compare it to the raspberry pi I also use; will be interesting.........

Next thing I encounter is that it will not play 24/192 files without hick-ups. It works fine with flac files up to 24/92. Is this some kind of buffer adjustment that must be made?

Kind regards,

[ldolse]

Unplug and then replug your USB sound device from the system after the system is fully booted, this should resolve the issue. This only seems to happen with some users and certain sound devices, haven't been able to figure out the root cause.

Keep us posted on that supersurfer; we dream that some day, maybe, Idolse will have some time to go for cheap (ARM) platform, RPi, Beaglebone (new cheaper HW coming) so we may have a mpdpup in every single room in the house and stop giving all the money to Intel (;-)

@ Jean Louis:
I will certainly do that! The advantige of raspberry Pi is that it is very small and inexpensive. Only problem is that there are issues with the usb/ethernet bus. Because USB and ethernet is going on the same bus there is an occasional package loss. This prevents the Pi from being able to run files with higher bitrate than red book.
The comminuty is trying to solve this problem with software.

Because I did not want to wait for that development I purchased the Alix and tried MPDPUP.

@Idolse:
switching off the alix board and starting up again has now stopped mpdpup to put signal out to WaveIO. I have tried unpowering-unplugging/repowering-replugging numerous times but I can't get the sound back.

The client is showing that music is playing.
Strange thing is also that when repowering always last the play queue is loaded that was playing when I had sound, even when putting in new playlists afterwards and repowering.

How can I unmute this?

Kind regards,

[ldolse]

Hi Supersurfer, the mute issue is a known issue for the WaveIO, refer to the second post to fix it:

Hi Idolse,

Thanks for the link, I missed that piece. It's working again.

I wll do some comparison between the raspberry pi and alix this weekend, keep jou posted!

Hi Idolse,

I would like to thank you for your work on this distribution! I am very happy with it, and as a linux noob I am able to get it working due to your interface and your help on this forum.

Once set up it runs very stable.
I have been trying the advanced adjustments but it does not always go through all the steps, using ssh.
I delete the save file and run the set up wizard again, then it does not configur the waveio.

Also; how can I select mpd 0.17? I do not see it in the set up interface.

As for comparison to the raspberry pi:
The pi runs less stable due usb buss speed problems (probably also because of different software), sounds less good (is this software or hardware related?).

But the pi is very compact and cheap! I am thinking of building a music player with the pi, a simple usb dac (pcm2707) and an sd card player. This could fit in a nice small hammond box so you can take your player with you on holiday together with a nice headphone amp and a pair of good headphones.

So it would be nice to have mpdpup also for arm boards but for now I am very happy with mpdpup on alix!

Kind regards, and keep up the good work!

[ldolse]

Glad it's working for you more or less. Regarding the advanced adjustments, I would need some more detail - I'm not aware of anything in that area failing, though there is a known issue where nrpacks is not applied and needs to be manually set.

MPD 0.17 can be set as default in one of the other menus of the wizard after the first time you run it - the system menu if I recall correctly.

ARM is a fairly low priority for me right now - other people in the Puppy Linux community are working on Raspberry Pi support, but I would need to port mpdPup to their system. The USB bus issues don't leave me much motivated, right now I'm having a hard enough time finding time for the changes for the next x86 release

Hi Idolse,

MPD 0.17 can be set as default in one of the other menus of the wizard after the first time you run it - the system menu if I recall correctly.

What do you mean with 'one of the other menus'? After first start up I go automaically through all the menu's in SSH. I know with a headed PC (screen, mouse, keyboard) you see more menu's but can these menu's also be made visible with the SSH connection? For Alix can not be run with a screen.

How do I manually set nrpacks?

You are right about your ARM priority, maybe if things develop in the future it might become more interesting..........

Kind regards,

After you run the wizard for the first time and reboot you can re-run the wizard at any time by typing 'mpdwizard'. I'm pretty sure the SSH welcome banner explains this. During the first boot it runs the setup wizard which you already navigated through. Subsequent runs will bring up a set of menus you can navigate through.

[Supersurfer]

Hi Idolse,

Thanks for your swift reply!

Found it! I'm a bit puzzled sometimes by all the information on this forum that I do sometimes not seem to find what I am looking for I feel a bit ashamed for asking you every time


I have been trying out Sox upsampler but this does not seem to work stable with Flac format. Using WAV works fine but FLAC gives hickups at some files and sometimes the Alix even crashes.

Can this be because of the low CPU speed and demanding tasks for decoding FLAC and upsampling at the same time?

Kind regards,

[ldolse]

No worries, I know there is a lot of info to absorb. Regarding Sox, yes, I doubt the Alix has enough CPU to do anything sophisticated with Sox, epecially if something else is taking up resources.

Hi Idolse,
thank you for putting time and effort for this project.

I'm using mpdPup for about a month and i am very pleased with it.

My new DAC just arrived and I had to make some changes because it does not work with standard alsa usb async drivers ....

Anyway I've downloaded and activated devx_mpdpup_0.9.3.sfs and kernel_src-2.6.39.4-patched.sfs (from http://www.puppylinux.com/development/compilekernel.htm) and tried to compile the module manually

Unfortunately:

# modprobe -v snd-usb-hiface
insmod /lib/modules/2.6.39/kernel/drivers/misc/snd-usb-hiface.ko
FATAL: Error inserting snd_usb_hiface (/lib/modules/2.6.39/kernel/drivers/misc/snd-usb-hiface.ko): Invalid module format

dmesg
snd_usb_hiface: version magic '2.6.39.4 SMP mod_unload modversions 686 ' should be '2.6.39 SMP preempt mod_unload 486 '

It seems that is compiled for the wrong kernel version and arch. Corect?

Could you point me in the right direction?

Thank you

[ldolse]

Hi cmiu, glad it's working overall for you. Regarding the kernel sources, thanks for pointing out the missing link. I uploaded them some time back, but forgot to publish the link. I've updated the first post, but you can get them here:
