no sound in fedora core 16

It looks an old problem from fedora 13/14...

The output of aplay -l have:

Code:

aplay: device_list:240: no soundcards found...

The output of lspci have:

Code:

00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)

The output of lspci -v have:

Code:

00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 04)
        Subsystem: Dell Device 04f5
        Flags: bus master, fast devsel, latency 0, IRQ 41
        Memory at 91a30000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: <access denied>
        Kernel driver in use: snd_hda_intel
        Kernel modules: snd-hda-intel

My system (uname -a) is:

Code:

Linux ******** 3.1.7-1.fc16.i686 #1 SMP Tue Jan 3 20:26:58 UTC 2012 i686 i686 i386 GNU/Linux

I have folder /sys/class/sound/card0/ but only have sub folder of hwC0D2 and hwC0D3. It may should have hwC0D1...

Any suggestion is welcome.

I just ran into the same problem.
Seems to be an access rights problem and unspecified default audio device, at least for me. Still working on the solution

Code:

#lspci -v
00:1b.0 Audio device: Intel Corporation N10/ICH 7 Family High Definition Audio Controller (rev 02)
	Subsystem: Lenovo ThinkPad T60/R60 series
	Flags: bus master, fast devsel, latency 0, IRQ 48
	Memory at ee400000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: [50] Power Management version 2
	Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
	Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
	Capabilities: [100] Virtual Channel
	Capabilities: [130] Root Complex Link
	Kernel driver in use: snd_hda_intel
	Kernel modules: snd-hda-intel

#alsamixer
-works and allows me to control the mixer and listen to my microphone

but it works only as root and not using the default device but only when selecting card 0

As user:

Code:

$aplay -l
aplay: device_list:252: no soundcards found...

As root:

Code:

#aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: AD198x Analog [AD198x Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: Intel [HDA Intel], device 1: AD198x Digital [AD198x Digital]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Sometimes when there are permission problems, by adding a regular user to group 'audio' will solve a permissions problem (one needs to logout/login of GNU/Linux after having done so). Having typed that, adding a user to group 'audio' should not be nominally necessary.
