No Sound in Fedora 16

Your sound card is not properly configured. I note:

!!Aplay/Arecord output
!!------------

APLAY

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

ARECORD

arecord: device_list:240: no soundcards found...

!!Amixer output

and I note:

[   17.132472] ALSA sound/pci/hda/patch_realtek.c:1358: realtek: No valid SSID, checking pincfg 0x4015812d for NID 0x1d
....
[   20.870626] <30>alsactl[951]: Found hardware: "HDA-Intel" "Realtek ALC268" "HDA:10ec0268,1179ff66,00100003 HDA:11c11040,11790001,00100200" "0x1179" "0xff66"
[   20.870639] <30>alsactl[951]: Hardware is initialized using a generic method

so the alsa sound driver could not detect the SSID to tune the alsa configuration for your PC's ALC268 hardware audio codec.

I assume you checked your BIOS settings to ensure your sound device is switched ON ?

I note these settings from the HD-Audio-Models.txt file from the alsa documentation ( a copy of which should be on your PC ) :

ALC267/268
==========
  quanta-il1	Quanta IL1 mini-notebook
  3stack	3-stack model
  toshiba	Toshiba A205
  acer		Acer laptops
  acer-dmic	Acer laptops with digital-mic
  acer-aspire	Acer Aspire One
  dell		Dell OEM laptops (Vostro 1200)
  zepto		Zepto laptops
  test		for testing/debugging purpose, almost all controls can
		adjusted.  Appearing only when compiled with
		$CONFIG_SND_DEBUG=y
  auto		auto-config reading BIOS (default)

and you could try forcing one of those model options on your Toshiba L305. Perhaps start with the model option 'toshiba'. You need to find the correct file to place that option inside. Possibly add the following line to the file (if it exists in Fedora, ...if not create the file) :

options snd-hda-intel model=toshiba

restart and test. If 'toshiba' does not work, try another option in the list.

Yeah; I noticed that too, but didn't know what to do about it. I'd like to point out that from the time I bought the laptop until I "upgraded" to F16, Sound Just Worked. I'll devote some of my Copious Free Time to trying your suggestions and report back.

The file to add that line might be /etc/modprobe.d/alsa-base.conf . . . <Not sure>

if above suggestion does not work you can also try OSS4.

To try it either use the binary closed source package here or there is also a open source package (the GPL licensed package is for Linux). I think the only disadvantage of the gpl package compared to the binary one is, that the installation takes a few minutes more time and deinstallation would be also more complicated.

Before you install it you should deinstall pulseaudio. You probably need kernel-devel and kernel-headers otherwise it will probably fail in the kernel module built process. As mixer you can use ossxmix afterwards. Commands to check if it works: osstest, soundon, soundoff

It's good that you use XFCE, because under Gnome 3 there would be pulseaudio dependencies...

Fedora16 has a group audio. Only root and members
of group audio have permission on
/dev/snd (ls -al /dev/snd)

Non-root users have to be added to this group.

I added myself to the audio group on my laptop. Nothing. Logged out, logged back in again. Nothing. And my sound mixer only shows a Dummy Output. Back when I was running F14, before I "upgraded" to F16, It Just Worked.

However, after a reboot, it worked fine. Weird, as the only change made shouldn't have required a reboot. And, if you need to be part of the audio group, why doesn't the upgrade take care of this?
