Any estimate on when this bug will be addressed?

Hello,
This bug affects me as well, BUT only if I try to install the modem
driver from LINUXANT ( http://www.linuxant.com ) using their automated
installer.
If I try to force reload the ALSA drivers; its a no go - the terminal
spits an error which states (something like, from memory) problem
What isn't immediately obvious to most people is that the modem itself
works fine, and the software driving the modem works fine. In Karmic
*the bug is in PulseAudio*, specifically how module-udev-detect
validates sinks and sources.

I am also affected by this bug. Everything was fine until I activated
the restricted driver for my modem. Upon reboot, no sound, and no sound
hardware registered in alsamixer or pulseaudio. Issuing 'sudo alsa
force-reload' restored sound and placed my sound hardware back in
pulseaudio's hardware
Switched to Lucid, bug is still present also there. Cannot use together

Hi all!
I'm using Ubuntu 9.10 and don't had sound but:
My souncard start working editing the file /etc/pulse/default.pa and commenting
the 4 lines mentioned in the comment #69 and restarting pulseaudio.
My Smart Link modem work properly with the sl-modem-daemon (no driver neded).
And i have
adding some more info =upgraded from maintained 9.04to 9.10 386i via
update manager and upgraded afterwards to UbuntuStudio 9.10, another
issue is that the System is not booting when my printer(USB MP220) is
connected.
Is there something wrong with the new device manager or GRUB2.
I can boot
I think I suffer on the same issue, the only way for me to get sound is
to open the terminal and to execute this:
sudo alsa force-reload
afterwards I get the sound, Everything is working than correctly, only
the internal microphone volume have to be adjusted.
Skpe is than also working
Downloaded the Karmic RC alternate iso, upgraded distribution from Jaunty, no
problem with sound.
Then downloaded the Final Release yesterday upgraded and the sound disappeared.
That was quite alarming.
As others have noted the sound card was not being recognised in Hardware
profile. Removing
I had the same issue - post number 14 here fixed it, commenting out the
lines like he said:
I've opened /etc/pulse/default.pa and commented 4 lines.

Hi, I'm affected by this bug too on a HP compaq nx6310, removing the
modem driver also seems to fix it for me.

Well, what if I want to use my modem ? It was working on Jaunty, so this is a
regression...and the above fix is just a workaround...
I know this is a proprietary driver, so we can't blame ubuntu dev...Anyway,
analog modems are less and less used so it's not a serious regression...
The SmartLink
After clean install (I did it yesterday so it's RC with newest updates)
I have no sound at all too. I tried workaround from comment #40 but it
didn't help.
When I was on Karmic but the one updated from Jaunty there was no
problem at all.

Sorry, now I red this workaround once again and removed sl-modem-daemon
then removed .purple and killed pulseaudio. Now sound works fine so
workaround is ok.

I can confirm that sound works after removing the modem driver in
jockey.

Analyzing the issue, the problem lies in module-udev-detect. It checks
for closed status on all PCM subdevices for the audio card:

As discussed on irc, udev-detect is doing the right thing here. We

Sound card was not detected for me either, I just got the dummy output.
Disabled the modem built into my laptop in hardware drivers and sound
started working immediately. Sound preferences now lists all my sound
devices under the Hardware tab.

This might be an upstream issue - this bug affected me (and commenting
out the udev loader fixed me) on my Gentoo machine at work, but I
actually had no problems with latest PA on my Karmic laptop at home!

Commenting 4 lines in /etc/pulse/default.pa as mentioned before helped
me too. But hardware tab is still empty (HP Mini 2140). No slmodemd is
here.

Experiencing this issue just as of today. Not detecting the onboard nor the pci
sound devices. Alsa detects them just fine:

OK, my bug is related to module-udev-detect, if I use module-detect
everything works out just fine.
