Hi,
Well I made an initial build with the moblin-image-creator. My first tests were with the standard config file (from moblin-image-creator) but they also didn't work. 


How do you suggest to make a build for my platform? Do you know if  
there is somewhere an document that is describing how to do this?

And the prefered method is using 'merge' script and then use that  
menlow spec file to compile the kernel for menlow. See those files  
under moblin kernel folder.

I already tried with the images from moblin itself but no go with

that.

You have menlow-like platform and if you are trying netbook  
platform, it should not work.



How do you mean adopt the config from generic + menlow? How can I do

this?


Obviously, the output of uname does not make sense. If I am not  
wrong, you just use moblin's source code and is using some config  
for netbook or some config from you by yourselve. So what I means  
is: using the config file named -- config-generic and plus the  
content from config-menlow (just a few lines totally) and then re- 
compile your kernel.

The kernel that I'm using is:

[r...@localhost ~]# uname --all
Linux localhost 2.6.29.rc7-40.1.moblin2-netbook #1 SMP Sun Mar 8
02:13:27 UTC 2009 i686 i686 i386 GNU/Linux

Not exactly sure the complain from the app.
Which kernel are you using? Can you adopt the moblin's config
(generic + menlow) and have a try?

I see there is nothing about pulseaudio into my /etc/initrd.d


However when I look into the installed rpm's then it's telling me  
that

pulseaudio is installed:

r...@localhost ~]# rpm -qa | grep audio
alsa-plugins-pulseaudio-1.0.19-2.8.moblin2.i586
pulseaudio-0.9.14-1.36.moblin2.i586
pulseaudio-devel-0.9.14-1.36.moblin2.i586
[r...@localhost ~]#


When executing pulseaudio from the command line I get:
[r...@localhost ~]# pulseaudio
W: ltdl-bind-now.c: Failed to find original dlopen loader.
W: main.c: This program is not intended to be run as root (unless --
system is specified).
N: module-alsa-sink.c: Disabling timer-based scheduling because high-
resolution timers are not available from the kernel.
N: module-alsa-source.c: Disabling timer-based scheduling because

W: alsa-util.c: Cannot find fallback mixer control "Mic".
Soft CPU time limit exhausted, terminating.
Hard CPU time limit exhausted, terminating forcibly.

[r...@localhost ~]#


when I then look into my dmesg I have this:
[ 3526.986325] hda-intel: Invalid position buffer, using LPIB read
method instead.
[ 3526.987836] hda-intel: IRQ timing workaround is activated for card

Can you try to (re)launch pulseaudio daemon and run alsamixer again?
pulseaudio --start
You should see pulseaudio running on the backgroud.

Hi,

Well we are developing our own HW. We are using the Silverthorne and
the Poulsbo (400Mhz FSB)

This is what we have on /dev/snd

[r...@localhost ~]# ls /dev/snd/
controlC0  hwC0D0  pcmC0D0c  pcmC0D0p  seq  timer
[r...@localhost ~]#



Also when I look if the pulseaudio is running I see this audio  
deamon

running:
[r...@localhost ~]# ps aux | grep audio

root       537  0.0  0.0      0     0 ?        S<   20:00   0:00

No, of course.


Which platform are you using? menlow? mrst? What kind of device  
node

under /dev/snd do you have?

Does that mean that when I'm logged-in as root the pulseaudio will
never start?

Hi,
You can try #alsamixer under normal user like "moblin". It works
ok on my device. It seems that pa server can't be launched
successfully under root privilege on moblin.

Thanks.

Hi,

I'm trying to setup my audio on my device with moblin. I tried
before

with ubuntu and this looks fine. It looks like I get the  
pulseaudio

not to work on moblin
I don't really know what is happening so I'll need some help.
When I look into /dev I don't see anything that I can use for
playing
a audio file (no /dev/dsp /dev/audio)

When I try to start alsamixer I get the following error:
[r...@localhost ~]# alsamixer

ALSA lib pulse.c:272:(pulse_connect) PulseAudio: Unable to  
connect:

Connection refused


alsamixer: function snd_ctl_open failed for default: Connection
refused



Can please somebody help me?
