No sound device on Ubuntu 7.10 (Gutsy Gibbon)

[Rostfrei]

Hello!

I have major problem and I have no idea how to solve it. I have tried almost everything. I'm doing something with pjsip library (it uses PortAudio) and it's test application.

I have Ubuntu 7.10 installed on two PCs with a different hardware. On both computers I configured alsamixer so I can record and playback my recorded voice with "gnome-sound-recorder 2.20.1". This way I checked if hardware and drivers are working on both systems and they do.

Now on the first PC the pjsip test application works ok, but on the second PC no matter what I do I always get errors that there are no audio devices and that application cannot start.

I decided to download the latest PortAudio tar package, compile/install it and run some of the test apps that come with it. On both I ran test application in tests/pa_devs.c.

Try checking the device file permissions on each machine:

    ls -l /dev/dsp*

You might need to use chmod as root to give group rw permissions.

    sudo chmod g+rw /dev/dsp*

Or try reinstalling a new version of ALSA on the bad machine.

that were solved by the above actions.)

It definitely was a permission problem, but it is not working yet. On the non working PC2 I have Asterisk installed.

>ll /dev/dsp*
crw-rw---- 1 asterisk asterisk 14, 3 2008-05-08 12:49 /dev/dsp

On the working PC1 nothing special is installed and there is

ll /dev/dsp*
crw-rw---- 1 root audio 14, 3 2008-05-19 16:10 /dev/dsp


On the PC2 I put myself in the 'asterisk' group and now at least the test application 'pa_devs' works (It would work yesterday, but I never tried to execute it with sudo).

On PC2 I get

I bothers me that on the PC2 there is shorter printout and 'Max outputs = 0'. Pjsip test application still doesn't work and when I start PortAudio test application 'pa_fuzz' I get

>./pa_fuzz
Segmentation fault (core dumped)

On the PC1 'pa_fuzz' works without a problem

>./pa_fuzz
Hit ENTER to stop program.


What else can I do to resolve the problem?

Hi Marko

 

If you're getting a segmentation fault you can always run the code in a debugger and get a stack trace of where the crash is happening...  but given that pa_devs is reporting no output device it's probably just that pa_fuzz is assuming an output device is present.

 

Perhaps you have some other process running which has captured the output channels so OSS isn't making them available?

 

Ross.
