Can't get any sound with OSS v4

R

Roberth

Hello

I have installed the OSS v4 soundsystem, since my soundcard isn't supported in oss in FreeBSD(cmi8788). I have started the oss init script, it detects my soundcard fine, everytime looks fine untill I play some sound, either with osstest etc, no sound at all, and no error messages, any tips where I can start to look?
 
I guess you've checked the mixer settings? (As a test, you can install aumix and pull everything to 100%.)
 
Fair enough - not that, then.
If the card has multiple outputs (line, headset, surround channels) it might have messed up the routing and be using the wrong one, so you probably want to check all of them.

Outside that, I'm afraid I can't really help you ...
 
I was thinking more "try plugging your speakers into every possible socket and see if one of them works".

As for testing, well - I've found "cat /dev/random > /dev/dsp0" works - it generates a fairly bland noise, but it's definitely different from silence, and will most likely be interpreted as plain 2-channel stereo.
 
Tried every single jack output, no sound.

EDIT: even with ossxmix it shows activity when playing music.
 
How very weird.
I'll admit I've never used OSSv4, so you'll have to hope someone with more experience in the field notices this.
 
I'm having a problem like this. I can't get any sound, anywhere.

Here's the rundown.
* Up until last Sunday I had two PCI sound cards and one built-in.
* The built-in is disabled in BIOS.
* The cards are M-Audio Audiophile 2496 and Creative SB Audigy LS (using a CA0106 chipset).
* Until Sunday I used the M-Audio card in FreeBSD 7.2 with OSS from ports (because the ordinary envy24 driver would hang my computer when switching between audio using software), while I use the Creative card in Windows for gaming (dual boot).
* So this Monday I did a portupgrade -a, after going through the UPDATING file.
* After the portupgrade, OSS started detecting both my audio cards, which it had not done before.
* My computer started hanging when starting KDE (4.3.1), right when the log in sound should start playing.
* osstest did work outside of KDE, though.
* I saw nothing of note in the X.org log (highest verbosity -- I think), it just cut short.
* I did have CPUTYPE and OPTIMIZED_CFLAGS defined in make.conf, so I commented them out and rebuilt everything I had upgraded since last time, just in case, which took another day and a half. This did not help.
* I tried downgrading the audio/oss port to the version before which I knew worked. This did not help either.
* I removed the Creative card, which did not change anything.
* Finally, when I tried using only the Creative card, my PC stopped hanging. But now I get no sound, on any sound output.

Currently, osstest is reporting that the Audigy LS sound card is working perfectly, and I am seeing no errors of any kind, anywhere. mplayer plays audio, but I hear nothing. KDE loads without hanging, and everything says that I should be hearing sounds, but I do not. When I raise the physical speaker volume knob to max (which is very, very loud), I hear a faint "boom" followed by a very faint noise when something should produce a sound. And sound still works in Windows (without having to change anything).

Oh. Yesterday I actually got it to work in FreeBSD for one whole session, without changing anything in particular. (Actually, I did deinstall and reinstall a few times, but that doesn't work now.) It stopped working after I rebooted the computer.

This is all so inconsistent. What in the world can produce this behavior? What options do I have to try to find out more about possible errors?

In the meanwhile, I'll try portupgrade -Rf audio/oss again...

What is the make and model?. if it's the ASUS D2/D2X - then yes the drivers don't produce audio - we're working on that. But most other devices should work.

post the output from cat /dev/sndstat.
 
Is the D2X working now? I only get sound from my onboard sound. :-/
audio/oss is installed and # osstest is working:
Code: 
Sound subsystem and version: OSS 4.2 (b 2002/201003241702) (0x00040100)

Still I don't hear anything.

Edit: Obviously, OSS v4.2 build 2002 from 8.0-STABLE doesn't support the D2X as support for it was added a month after the release. :\ Any chance to get it working anyway?
 
So, now I compiled OSS from source and installed it and both my onboard Intel HDA and the Xonar D2X get detected.

Strangely, if I don't # kldload snd_hda first and unload it and execute # soundon afterwards, the machine freezes when starting X. I was hoping to be able just to use the 4Front OSS driver, but obviously, that doesn't work for me. :\

Any hints?
