upgrade to karmic lost sound

[Max Seckel]

after upgrading my daru3 from 9.04 to 9.10 i lost all sound.

i followed the upgrade instructions here http://knowledge76.com/index.php/KarmicUpgrade (re-enabled software sources, installed system76 drivers, rebooted, etc).. and upon rebooting realized there was no sound. if i go into sound preferences and then the hardware tab... it lists no devices at all, and the output tab only has settings for "dummy output".

[Max Seckel (maxpth)]

after some searching i found that...

sudo also force-reload

works to bring back sound.. but needs to be done after every reboot.

slightly unrelated but just annoying is that some time after re-enabling sound i noticed there were two volume control applets in the panel. i right clicked one and hit remove.. and they both disapeared and there seems to be no way to bring it back (it doesn't show up in the 'add to panel' menu).

well that didn't really help at all. still no sound and doing the previous fix (alsa force-reload) now fails and gives me a ton of errors. additionally.. while there is no volume control on my panel i've also lost the wireless applet too which is annoying since i now (after upgrading) lose my wireless connection every time i come back from suspend or hibernate.

[Huggie (matt-huggins)]

I lost my sound too, and trying various of these "fixes" did nothing.

[Tomas Aragon (taragonmd)]

I also lost sound after upgrading from 9.04 to 9.10

I tried this fix but it DID NOT work:

This works but must be repeated after each reboot:
sudo also force-reload

[Tomas Aragon (taragonmd)]

Correction: sudo alsa force-reload

[Thomas Aaron (tom-system76)]

We will run some tests on this Monday or Tuesday.

Sounds like a hosed upgrade, though. We're not seeing this on freshly imaged machines in the shop.

[Thomas Aaron (tom-system76)]

If you go to System > Administration > Hardware drivers and disable the proprietary driver called "Modem Software", and then reboot, does that fix the sound?

[Huggie (matt-huggins)]

Thomas - removing the Modem Software driver fixed it for me, thank you so much! :D

[Tomas Aragon (taragonmd)]

Yes, removing Modem Software restored sound! Any downside to removing Modem Software?

[Nicole Ackerman (ackey)]

I fixed my sound by fixing my menu.lst since I had still been booting with the old kernel.

[laptoplinux (laptoplinux)]

Removing software modem also did the trick for me.

[Artur Efimov (arturefimov)]

I haven't found that menu item "Hardware drivers" in "System" > "Administration"...
Something else fixed the problem for me, I have completed several instructions while fixing the bug and nothing helped (despite I rebooted my system each time), but today morning I just turned on my computer and the sound worked!..
