The soundcard is an Aztec AZT2320, PnP but ISA connector. It was working before under W98. I installed Blag10000 (default desktop option)- the card appeared to be detected and configured, there were no error messages, but there's no sound.

The speaker symbol bottom right on the toolbar has a line through it. If I right click and open volume control I get a message that it's not working. The detail says invalid mixer device, /dev/mixer can't be opened. /dev/mixer exisits as a zero size file, I've tried changing permissions and also running as root, but no difference.

Similarly, if I try to use XMMS, I get a message that audio couldn't be opened. Somewhere in fiddling about, I've had a message that /dev/audio can't be opened - like /dev/mixer, it exists as a zero size file.

Any suggestions please? Go easy on me, I'm newish to Linux (very new to Blag) and I'm very much a user rather than a programmer.

Thanks

Steve

Try either of these commands as root:

Code:
redhat-config-soundcard
sndconfig



(note in blag20k it's system-config-soundcard)

[quote="jebba"]Try either of these commands as root:

redhat-config-soundcard

returns 'no soundcard detected'

sndconfig

This detects 'AZT2320 PnP Sound Device:Audio'
It offers some address and IRQ settings to match DIP switches on the card - there aren't any switches.... I accepted the offered settings (0x530/IRQ5/DMA1-1/DMA2-0) and it then went to play a test sound, returning the message 'error opening /dev/audio'.

I tried the other address setting, but everything hangs when it goes to the test sound. I got the IRQ as 5 from the screen during boot.

Is there anything else to try?

Thanks

Hmm....

You could try the alsa sound drivers...

Code:
/usr/sbin/alsaconf


ALSA=Advanced Linux Sound Architecture

Its the next generation of Linux sound drivers and are the default in kernel 2.6 (e.g blag20k & fedora core 2).

Note, alsa sets its channels to mute by default. You can change levels with (also in the menu):

Code:
gnome-alsamixer

alsaconf appears not to be installed. I couldn't find an option to install the alsa suite under the 'system settings/install apps' menu. I started to read the alsa project pages but quickly got out of my depth.

I tried to install the gnome-alsamixer using the 'install apps' menu, but it just comes up with 'there was an error' popup, whether I do is as a user or root.

Further info, just noticed when shutting down:

A Gnome pop-up comes up saying mixer-applett2 crashed with a segmentation error.

Later, in text mode, there's a modprobe error - sound service-0-0 not found, followed a line starting aumix: with an error (sorry. missed what it was in detail, and I don't have time to re-run before going out).

Does any of that help?

Thanks,

Steve

Swapped the Aztech card for a cheapo PCI one from my Suse box, all ok now. Suse seems happy with the Aztech too.
