No sound in LXDE, all suggestions tried (bit long) (Solved)

[scbs29]

I have no sound on my LXDE installation.
The soundcard is reported in pcc as a CA106 Soundblaster.
pcc Sound Configuration shows the driver as
Intel HDA driver (snd_hda_intel[ALSA])
Enable PulseAudio and Use Glitch-Free mode are both checked.
Click OK and the driver is shown as
CA0106(snd_ca0106[ALSA]) with the same two checkboxes checked.
The above is after installing PulseAudio. Before I installed
it I had no sound either and I installed it following advice in this forum.

I tried alsaconf and that did not work.
Alsaconf suggested running gmixer. I did this and received

** Message: pygobject_register_sinkfunc is deprecated (GstObject)

I then decided to try other suggestions in this forum
about volumecontrol. I have no volume control icon in my
system tray.
I tried all of the suggestions in both
http://www.pclinuxos.com/forum/index.php/topic,102848.0.html
and
http://www.pclinuxos.com/forum/index.php/topic,96730.0.html
but nothing makes any difference. I still have no volume icon
and no sound.

Can anyone help ?

The above is after installing PulseAudio

I know (in KDE at least) that after installing Pulse Audio the system needs a full reboot to work correctly

[scbs29]

Tried restart pc, full reboot, logout and back in again.
None made any difference.

[scbs29]

Saw somewhere in the forum about typing volumeicon on a CLI.
Tried this and got:
volumeicon: alsa_backend.c:88: asound_get_volume: Assertion `m_elem != ((void *)0)' failed.
Aborted

[daniel]

What is the output from

Code: [Select]

pulseaudio ?

[scbs29]

Just rebooted pc.
Volume control was on taskbar. Opened it and the output volume was set to 0.
Changed it to 100, made no difference, still no sound. Then the volume control disappeared again,
and so did the start menu. Rebooting - no volume control, no sound but start menu back.
Output from pulseaudio as cli is
E: [pulseaudio] main.c: Daemon startup without any loaded modules, refusing to work.

[daniel]

My output

Code: [Select]

pulseaudio
E: [pulseaudio] pid.c: Daemon already running.

so...
Search for task-pulseaudio-remove, install it, this will remove all pulseaudio package, and configuration files.
Reboot
Now install task-pulseaudio, and then go to pcc to enable pulseaudio
Reboot
What is now the messages  from pulseaudio?

[scbs29]

Thanks for the message
I did as you suggested. I now have 3 volume controls on the task bar.
Output from pulseaudio is now
E: [pulseaudio] pid.c: Daemon already running.
E: [pulseaudio] main.c: pa_pid_file_create() failed.

[daniel]

And sound playing?

[monsee]

I have too an Intel HDA driver (snd_hda_intel[ALSA]) Sound Driver.
And I had sounds on my PC (PCLinuxoS LXDE Edition, of course) when I disabled Pulseaudio and reboot my PC.
Today (many times after) my sound works good the same (no Pulseaudio allowed, in my PC).
Can you try to disable Pulse audio and -after that- reboot your PC?  

[daniel]

when i disable pulseaudio, i can let play only one application, if i have then deadbeef in task panel, i can't hear audio from youtube, but when i exit deadbeef i can hear sound from youtube. But this is for me a no go. So i have enabled pulseaudio...

[scbs29]

Daniel - sorry, should have said, still no sound.

monsee - uninstalled pulse - no difference, still no sound.

ran through troubleshooting again.
differences were

gmixer now gives error

aumix -q now gives
dig1 100, 100

all other results were the same.

BTW, sound OK when I boot into XP. I was beginning to think the soundcard
had died until I tried this.

[ghostbunny]

did you try alsamixer?

open a terminal and type alsamixer and press enter.

you can navigate with the arrow keys, Fx whilw x is number between 1 and 6 or so and Esc and enter.

Turn up everything which is not related to Mic and Micboost.

also try F6 for checking whether the correct sound card is selected.
if not select it.

If all of this does not help log in as root on a terminal and enter alsaconf and reconfigure alsa.

[daniel]

Thanks for the message

This seems so good, and you have not checked that all channels not muted ?

When i mute my audio, and hit then again the mute key i have to check after this that all channels are on. Master, speaker, and headphone. Most time is only master on, and the others of... 
Gmixer should work, when pulseaudio is working, when not you can try as root

Code: [Select]

alsaconf and then check again, that there is nothing muted...

[scbs29]

Thanks for all of the advice.
The 3 volume control icons have now disappeared again, but when they were there they all showed 100%,
none were muted.

I have now uninstalled pulseaudio to see if that made any difference.
I opened alsamixer and set it as follows:
ALsaMixer v1.0.25
Card: CA0106
Chip: CA0106
View: Playback

Bars
Master set to 100, Item: Master [dB gain: 0.00]
S/PDIF small square with MM in it. Item: S/PDIF [Off]
S/PDIF C set to 100, Item: S/PDIF Center/LFE [dB gain: 12.00,12.00]
Same settings for S/PDIF F, S/PDIF R, S/PDIF U,
Analog C, Analog F, Analog R, Analog S.


I then ran alsaconf as root, with the following:
AlsaConf
Following cards found
ca0106 Creative Labs CA0106 Soundblaster (highlighted.)
Configuring snd-ca0106
Do you want to modify /etc/modules.conf ?
Yes
Will prepare the card for playing now
will run alsasound init script then
amixer to raise default volumes
Loading driver
Doing alsactl to store mixer settings
