I feel I shold be able to fix this but having tried a couple of things I'm still not getting anywhere. I've got no sound on my Fedora 10 64 bit installation. I've installed Skype and though the text chat works fine, sound doesn't.
I've tried other applications (Rhythmbox music player set to a radio channel) and even though through PulsAudio volume control I can see what I feel is output its not getting to the speakers. They're not muted before someone asks . . .
The only clue I get is that in the skype terminal I see
ALSA lib control.c:874snd_ctl_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_ctl_pulse.so
I get the same error as above. After the chmod I still have no audio. What is interesting is that it is after one of the recent updates that I lost the sound on FC10, so I used to have sound.
control "IEC958 Playback Default" (index -1) not found
The link to the output from my alsa-info is http://www.alsa-project.org/db/?f=44...a9ba4c6d721324
thanks

I solved the problem for my setup. On the commandline I ran 'alsaunmute'. Does that work for you as well? It was not possible for me to perform the same action in the PulseAudio Volume Control application.

Same problem happens here. Would you guys try to listen to music from you HEADPHONE? I cannot here any sound from my laptop speakers; however Fedora sound system (listing, recording etc) works well with my headphone and microphone. My laptop speakers are in perfect conditions. They work in Windows XP installed on the same computer with Fedora Core 10.
In System >> Preferences >> Hardware >> Volume control, we can mute/unmute sound of Headphone, Front (speakers) and IEC958 default PCM. I tried mute/unmute but the operations work only on headphone.
Yes!! A step forward. I too can get sound through a headset plus I can hear myself through a mic. Still can't use Skype, when I try to call someone I get a pop-up window saying "Problem with Audio playback". I'll try a note to the Skype people to see what they say . . .
Hi, I also have this problem (sound bars move correctly in pulse audio volume control, `iecset audio on` reports the same error as above and the same for alsaunmute) However to confuse the issue even more I have found a really inconvenient way to fix the problem. If I right click on the KMix speaker icon in the task bar and select Mixer to get the mixer window and then change the volume on the PCM slider, sound suddenly starts working again. I should be clear here - the PCM slider is not muted, nor is the volume low but it seems that in my case, changing the volume on the slider even a little will cure my sound issues.
Does this fix work for anyone else who is having this problem? And can anyone offer an explanation?
The laptop is a dell inspiron 8200 with intel integrated sound. I have had this problem both with fedora 9 and 10.
Thanks etc.

oh I should add. The sound fails again as soon as i restart the machine. though logging out and switching users does not kill the sound. This is why i say the fix is inconvenient - sound works but i have to mess with the volume control every time i boot up.

Confirmed. Using "nVidia Corporation MCP51 High Definition Audio (rev a2)", fiddling with the PCM control gets the audio back. alsaunmute and other tricks as mentioned earlier do not work.
Though I have to mention, "no sound" is a bit of a stretch, as I hear silent crackling sounds when doing audio playback after a reboot. These go away once I get the sound back by touching the PCM control in KMix.
This sounds like a bug in alsa, not pulseaudio related. My guess would be, that after a reboot alsa uses the wrong sampling rate and detects the correct one only when the PCM is modified. That's my guess based on the cracking sounds I hear, nothing more.
I'm running a fresh up to date copy of Fedora 10, x86_64.
