[all variants] Sound disabled after suspend/resume on Vostro 1510

[Frem]

Sound does not play in any application after suspending and resuming my Dell Vistro 1510 laptop. It will work after a reboot.

I read here that unloading and reloading the module works for some people.

# rmmod snd_hda_intel
ERROR: Module snd_hda_intel is in use

# rmmod $(lsmod | grep snd | cut -d " " -f 1)
ERROR: Module snd_hda_intel is in use
ERROR: Module snd_hwdep is in use by snd_hda_intel
ERROR: Module snd_pcm is in use by snd_hda_intel

ERROR: Module soundcore is in use by snd

# rmmod snd_hwdep
ERROR: Module snd_hwdep is in use by snd_hda_intel

Any help on module options which fix this, reloading the module, or reloading the module automatically after resume from suspend would be appreciated.

Hi:

I have the same problem I guess the module unload problems are due the fact that we still have apps running which are using sound (maybe even GDM) please let me know if you find a solution or work around

BTW is your ethernet working ?? because mine isn't (just wireless)

iamvaz, This is from my install notes (avalible in my sig)

Getting the Ethernet card to work from: http://www.stupent.at/2008/06/22/ubu...1510-a-review/ Giuseppe Says: July 11th, 2008 at 09:02 Hi there, I’m currently using ubuntu 8.04. I had serious problems with the Realtek RTL8111/8168B Gigabit Ethernet controller (all packets dropped). The module name is r8169. I would like to report that I was able to fix the issue by passing the pci=nomsi parameter to the kernel at boot time. (edit /boot/grub/menu.lst) -- Additionally, I had to disable the option in Windows Vista which allowed the hardware to be disabled to conserve power.

GDM is not using the sound card. You can check this with the following command:
sudo fuser -v /dev/snd/*

The only thing I've got using it right now is pulseaudio, which should theoretically be handling all that stuff? Or not? I'm not really sure how it works, though I'll probably end up looking that up if nobody else finds a solution.

This Launchpad bug seems relevant.

Temporary fix!
Running "sudo /sbin/alsa force-reload" will reload the sound drivers!

(...and crash the Gnome volume control applet and Firefox, both of which were probably trying to use sound)

Thank you !

Strange... For me, it restores the annoying beep in the terminal, but not the real sound that I want to hear.

Curioser and curioser...

I'm x64, if that makes andy difference.
