If I use alsa-mixer HDA Intel PCH (Alsa mixer) my sound for Master, headphone and speaker(s) is not muted. So these devices should be live -- I think.
But not a sound. Where do I look and what do I fix?
I sometimes have some strange effects when muting kaffeine on my XFce based Multimedia-Box. The sound cannot be unmuted then.
I have to start the kde-mixer kmix where I then can unmute the sound again.
This happens not very often but I have found no other workaround yet

Edit: I just realized that you seem to have two sound-devices. In some mixers (kmix for sure) you should be able to "switch" between them.
Thanks ReinerS, You give me an idea, which is to find out how I switch between those two "cards". The other thing I can try is to "mute" and then "unmute" the channels. We'll see what happens.
Well, in the xfce-mixer it should be a field right below the top where you can select it. Mine here on my laptop says "HDA ATI SB (Alsa mixer)".
Kmix however seems to work via the systemsettings and is bound to pulseaudio on my boxes.
On the Box which gives sometimes Problems I can switch between "HDA NVidia" or "SAA7134" (the TV-Card).

Thanks for the help ReinerS. What I know at this point is that I cannot get a sound out of this box. It is a Clevo machine sold by System 76 and it comes with Unbuntu pre-installed. Not being a fan of that system I usually replace it immediately with either Debian or Xubuntu. In this case I used Xubuntu and also Linux Mint Debian Edition, both of which are fully functional. I expected siduction to work equally well because it usually does, but not this time. I have crawled over the mixer and the various multimedia apps without success. I initially installed siduction with KDE, then pulled that and reinstalled using XCfce. No luck.
BTW I have only one sound card if we are talking about input/output. The second card appears to be an output-only HDMI device. I would understand that as something that would be used if I were routing sound through my HDMI plug(s) to some sort of external sound system.
In any event this does not work so my remaining choice is to decide the fate of siduction, which has been one of my favorite systems.

Did you try sound in a siduction Live USB stick session?
What does "aplay -l" show?
Somewhere there is guidance about reversing the sequence of cards when they are wrong in the installed system -- I think it is the Debian sound wiki.
Those "second" cards are sometimes pretty nasty, especially when they use the same driver module. I remember some issues where one had to provide a special file (asoundrc I believe) to sort out which card should be card 1.
Under http://wiki.ubuntuusers.de/.asoundrc (http://wiki.ubuntuusers.de/.asoundrc) is a explanation of that for ubuntu in german.
And also in our wiki http://wiki.siduction.de/index.php?title=Mehrere_Soundkarten_verwalten (http://wiki.siduction.de/index.php?title=Mehrere_Soundkarten_verwalten)
Also http://alsa.opensrc.org/Asoundrc (http://alsa.opensrc.org/Asoundrc) in english
Did you try to switch the soundcards with xfce-mixer ? Which cards have been shown in there ?

I would use pulseaudio and disable hdmi.
I have the same symptoms with 13.2.1 kde amd64 on an HP Pavilion notebook (http://h10025.www1.hp.com/ewfrf/wc/product?product=6883367). Sound has always worked just fine before, so I do not know where to begin.
I have changed the kmix settings several times. At first, it would not recognize that there was sound hardware (e.g., the speaker icon was greyed out). Now the software seems to recognize it, but there is still no sound at all.
vlc complains:
Audio output failed: The audio device "default" could not be used:
No such file or directory.
Here is the aplay output:
$ aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: HDMI [HDA ATI HDMI], device 3: HDMI 0 [HDMI 0]

First of all: kmix is not a good tool, use alsamixer. Secondly: do you use alsa or pulseaudio? the latter is very usable by now and mightfix your problem,. you could also check systemsettings/multimedia.

Again:
ZitatI would use pulseaudio and disable hdmi.
After installing pulseaudio and turning off HDMI, there is now music to my ears. This is an area I should learn more about. Thanks!
Just disabling HDMI always works for me. I have never tried pulseaudio as ALSA has always functioned perfectly by itself.
