Default Flash/AVI/Skype sound issue in Squeeze

Hello list,

I'm having trouble with my sound in a rather fresh Testing box on KDE.
Before I lay down the situation, let me clarify that I have googled,
rather extensively, in pursuit of a solution to my problem, yet I have
not found a solution that solves my problem. So, instead of turning my
system into a bundle of conflicting packages very possibly unrelated
to my problem, I decided to post my inquiry here. Now to the
presentation:

My sound works well for system sounds and notifications, such as the
music playing when logging into KDE and when emptying the trash. I can
also listen to music through Amarok and have sound from games as well
(namely, Tremulous). However, I do NOT have any sound from flash
player (I have installed flashplugin-nonfree) in both Iceweasel and
Konqueror or any sound from AVI videos (tested through vlc). I also
get a "Problem with Audio Playback" when making calls through Skype,
but I can live without Skype.

Here is what the "iceweaselrc" file says about my /dev/dsp wrapper for
iceweasel:


jason@debian:~$ sudo nano /etc/iceweasel/iceweaselrc

# which /dev/dsp wrapper to use
ICEWEASEL_DSP="aoss"

I have tried setting it to all the other values that the iceweasel
manpage says there are, yet still no luck.

Here is what lspci -v says about my hardware sound (I have omitted
output unrelated to audio devices or controllers):

jason@debian:~$ lspci -v

00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio
Controller (rev 02)
Subsystem: Intel Corporation 82801H (ICH8 Family) HD Audio
Controller
Flags: bus master, fast devsel, latency 0, IRQ 22
Memory at fdff8000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>
Kernel driver in use: HDA Intel

01:00.1 Audio device: nVidia Corporation Device 0be2 (rev a1)
Flags: bus master, fast devsel, latency 0, IRQ 10
Memory at fcffc000 (32-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>

And below are some screenshots from system settings->multimedia

http://s128.photobucket.com/albums/p190/Bulgarian_Toothpaste/?action=view&current=multimedia2.png

I have installed the following packages possibly related to my issue,
after googling a bit:

libasound libasound2-doc alsa-base alsa-utils alsa-oss alsamixergui

May I also note that after running iceweasel with an "aoss" wrapper

jason@debian:~$ aoss /usr/lib/iceweasel/iceweasel

I see the following output on the terminal, repeated constantly:

ALSA lib pcm_dmix.c:1010snd_pcm_dmix_open) unable to open slave

Yet I still get no sound.

I'd like to add that I've examined the terminal output after choosing
my Debian partition from Grub and noted the string:

Setting up ALSA... done.

kmix is well set and configured, and so is alsamixergui.

Might there be any solution to my problem?

I believe this is all I can provide you with for now, please do not
hesitate to ask for more information and I shall give it.

Thanks,
J

Hi,
I got a similar problem having a web cam with integrated microphone.
Restarting the computer with the web cam unplugged would bring back the sound
in iceweasel. Blacklisting snd_usb_audio in alsa-base-blacklist.conf did solve
the problem, in a not too nice way, but it did what I wanted. Of course, I
cannot use the microphone on the web cam now, but I really don't care for it.
Hope it helps
Thierry

Hello Thierry,

For reasons I have yet to explain my .avi and flash sound indeed
worked once I unplugged my Logitech USB microphone and rebooted. Right
now, what I need to do is blacklist it the same way you blacklisted
the microphone component of your camera, because I also have a Windows
partition in which the microphone is fully operational and needed, and
I don't want to have to plug it in every time I log into Windows. This
is my alsa-base-blacklist.conf:

jason@debian:~$ sudo cat /etc/modprobe.d/alsa-base-blacklist.conf
# Uncomment these entries in order to blacklist unwanted modem drivers
# blacklist snd-atiixp-modem
# blacklist snd-intel8x0m
# blacklist snd-via82xx-modem
# Comment this entry in order to load snd-pcsp driver
blacklist snd-pcsp
# Comment this entry in order to load pcspkr driver
jason@debian:~$

I added the lines

# Blacklisting microphone input
blacklist snd-sb-audio


But the problem persists. I think I might have something wrong with my
syntax. Here is what lsusb says about my mic (other USB devices
ommitted):

jason@debian:~$ lsusb
Bus 005 Device 002: ID 0556:0001 Asahi Kasei Microsystems Co., Ltd
AK5370 I/F A/D Converter

What should I do to keep my mic connected to the box, but not have it
interfere with my sound the way it did?

J

Yes it is
snd_usb_audio
pls note the underscore.
As far as where the real problem is, I hope someone here will be able to
explain more. And my guess is that there is a better solution than the one I
gave you. Any help/tips are welcome.
Thierry

Default Flash/AVI/Skype sound issue in Squeeze

Hi guys

This line in /etc/modprobe.d/alsa-base.conf did the job for me:

options snd-usb-audio index=-2

I stumbled over it because I had to do the same in order to make sound
on my Mac Mini work. This doesn't render the device unusable AFAICS, so
blacklisting it isn't needed. Thanks for your hints, my sound is back. :-)

What I don't get though is this: Sometimes the sound would have come
back earlier after updates, and sometimes sound didn't work for flash if
the .adobe and .macromedia folders were present in my home folder.
Strange, no answers to that. Whatever. The current solution works.

HTH, šndu
