HOW DO I EXIT???

Look at the pictures below. I stuck it on a menu that is launched from a button with a GEARS ICON on...

What is the difference between ADD+ and OPEN
Add+ Adds files to the current playlist
OPEN Opens a playlist (.m3u) file.

Don't get it wrong... as opening a music file by mistake in the OPEN PLAYLIST dialog hangs the app... - FIXED in V1.1

Are there any demo tunes?
Yup, a procedurally generated one via csound, a gentle remix of Cyra morgan (by twobob) and a chopin piece by Brad Hill. and Dance Cleopatra from this album by ZamalSka

DOES THIS WORK ON A PAPERWHITE???
Err. No. Amazon has neutered all devices later than the Kindle 5 as far as sound is concerned.

How do I get up the menu thing at the bottom?
Look at the 4th picture I posted. It's that button.


GOT ANY MORE FREE TUNES FOR ME TWOBOB?
well since you ask:
FILL YOUR BOOTS (558MB - 52 free tunes)

And I shoved two bonus tracks in a zip for ya too...
(One of which is used to demo out radio equipment world-wide)


Version 1.1 fixes all known bugs. (and adds jack backend support FWIW)

Enjoy.

[twobob]

Reserved.


EDIT: noted 1st bug...

./interface/gtk2/PlaylistWindow.cpp:	filechooser = gtk_file_chooser_dialog_new(_("L:D_N:dialog_ID:Choose.file.or.URL_M:true_RBK:true"), main_window, GTK_FILE_CHOOSER_ACTION_OPEN,

That should be RKB... ah well. Have to wait till tomorrow. Actual impact is ZERO.

FIXED IN V1.1

[brianinmaine]

Awesome. Yet again. You 'da man. Thanks!

[twobob]

Looking into the NAS support. (which IIRC I built in)
http://www.ibiblio.org/pub/Linux/app.../nas-1.2p5.lsm

perhaps this could push audio on a Paperwhite across the network to an audio enabled computer... Meh. why not.

http://packages.debian.org/sid/alsaplayer-nas

[brianinmaine]

Seems to me if you have a pc waiting for a stream, you might as well just play it locally on the pc. not worth too much effort IMO.

[twobob]

Because... you can do it sat far away...

and "you can" :P

(here is a nice guide to many things audio that I actually already know inside and out but meh)

I did just briefly check how close 0.99.81 IS to 0.99.80... Answer... quite far.

So if someone fancied updating this to the code from: https://github.com/alsaplayer/alsaplayer rather than the debian source I used, that ould be a manual process as the files have quite a few differences in them (too much for patch)

Word to the wise.

[brianinmaine]

Sounds like am assignment for someone, cough cough. I have some family things coming right up, we'll see.

[twobob]

no pressure.

I'm fiddling with nas

DOH !

will dig more...

[twobob]

http://manpages.ubuntu.com/manpages/...nasd.1nas.html

http://manpages.ubuntu.com/manpages/...conf.5nas.html

[brianinmaine]

Not much info??

About 3/4 down the page
http://home.icequake.net/~nemesis/bl...hp/archives/95

not much web info at all!

[twobob]

Finally. After like a 100 searches I found a page..
http://radscan.com/nas.html

and a pitiful support list
http://sourceforge.net/p/nas/discussion/705744/

a woefully underpopulated wiki
http://sourceforge.net/apps/mediawik...itle=NAS_Links

and a very hard to parse mailing list
http://radscan.com/pipermail/nas/
what joy.

will dig

[twobob]

Okay for the next poor soul:

me@dev /usr/local/src $ nasd -aa &

Network Audio System Release 1.9.3
Error binding unix socket: /var/run/nasd/audio0
: Address already in use

Fatal server error:
Cannot establish unix listening socket

if we STRACE that we note that the ordinary user account DOES NOT HAVE PERMS to create the socket..

run it as sudo

(To kill it you will have to sudo killall -9 nasd, from another term, sigh)

also we have to check the devices

The alsa drivers have native sound-devices in the /dev/snd/ directory. If you have one card you might see the following devices:

/dev/snd/pcmC0D0 - the raw audio device for the card
/dev/snd/mixerC0D0 - the mixer for card 0
/dev/snd/controlC0D0 - the control device for card 0
The first number means the number of the soundcard, the second number (if any) is the number of the device. A sound card with two PCM devices would have a pcmC0D0 and pcmC0D1 device. Please note: the ALSA devices have changed between the previous version. Older ALSA drivers use /dev/snd/pcm00 (first number is the card, second number is the device).

so:
(REF: http://www.tldp.org/HOWTO/Alsa-sound-6.html)
me@dev $ ls /dev/snd/
by-id by-path controlC1 pcmC1D0c pcmC1D0p seq timer

c = capture
p = playback (I finally figured out)


I tweaked the config to give us some debug

EDIT: noted in docs you can put "" in mixer section - this is honoured despite only being documented as for voxware... That gets rid of the mixer errors:

me@dev $ sudo nasd -aa -config ./nasd.conf

config: Maxfrags set to 3
config: Minfrags set to 2

hmmm... dodgy.

hmm. a bit better.



next up we maybe? need to open up our X tcp sockets ( no listen tcp is a standard these days)
me@dev /usr/local/src $ socat TCP-LISTEN:8000 UNIX-CONNECT:/tmp/.X11-unix/X0

and nerf our access control
me@dev /usr/local/src $ xhost +

access control disabled, clients can connect from any host

Let's try running nmap on the kindle...

[root@kindle bin]# LD_LIBRARY_PATH=../lib:$LD_LIBRARY_PATH ./nmap 192.168.1.69

Starting Nmap 6.00 ( http://nmap.org ) at 2013-10-05 13:06 UTC

humph STILL no port 8000...


on the kindle:

[root@kindle root]# AUDIOSERVER=192.168.1.69:0 /mnt/us/extensions/alsaplayer/alsaplayer -o nas

but at least that is one step closer...


working on it...

bonus. That is working at least now.

[twobob]

Wel.. I did finally get it (NAS) to AT LEAST run locally.

Now when I say "run" I mean startup, show the port, run clients - but make NO sound.

sigh... so yeah. networked audio. As much fun as kicking yourself in the head.

I kind of recall Geekmaster pushing out /dev/audio over ssh. perhaps that would bear looking at.

As for NAS. little joy for lots of work.

http://www.alsa-project.org/~tiwai/OSS-Emulation.html could be a way forward to fix my issues...

on the plus side: http://stackoverflow.com/questions/1...98512#19198512 I shared what we learned.

C'est la vie.

Nice to know it's not ONLY me
