[SOLVED]Sound works only in phonon

Question

Good evening,
I'd like to know why I can hear nothing. I've tried lots of solutions, but none has worked fine. But strangely the tests in Phonon work.
My sound cards are:
card 0: MID [HDA Intel MID], device 3: HDMI 0 [HDMI 0]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: MID [HDA Intel MID], device 7: HDMI 1 [HDMI 1]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 0: ALC892 Analog [ALC892 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: PCH [HDA Intel PCH], device 1: ALC892 Digital [ALC892 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
And the one that should work is the 1,0; I can tell you that because it works in Phonon.
- I've checked out both alsamixer and Kmix and the channels were unmuted.
- I've tried to set the default sound card using a global asound.conf.
- I've checked whether all modules have been loaded correctly
- Trying to play something with aplay, the device is busy
- In the UEFI, the audio is enabled
The issue is always the same:
ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave
Playback open error: -2, No such file or directory
I think I've written everything, I'm sorry if I haven't.

Answer 1

I just had an issue with no sound after recent updates.  Not sure it's the same problem you are having. 
I found I had to open Audio Mixer, select Sound card: HDA Intel PCH (Alsa mixer), Select Controls, check box for Speaker and check box for Headphones.  After doing this I found the Speaker volume was set at minimum (although Master and PCM were already set at maximum).  Adjusted Speaker volume up and I finally had sound again.
