[gentoo-user] need sound to listen to a adobe flash video

[gentoo-user] need sound to listen to a adobe flash video

[Valmor de Almeida]

Hello,

I would appreciate some guidance in getting sound working such that I
can listen to an adobe flash video. I am using firefox (have the adobe
flash plugin installed which plays video but no sound) and a pretty
updated gentoo laptop.

Thanks in advance.

Try lspci -v and see if the sounds card is using a driver.  If it is,
then the kernel is working and it is recognizing the sound card.  This
is what mine looks like:



01:0a.0 Multimedia audio controller: Creative Labs SB Live! EMU10k1 (rev 0a)
        Subsystem: Creative Labs SBLive! 5.1 eMicro 28028
        Flags: bus master, medium devsel, latency 32, IRQ 18
        I/O ports at b000 [size=32]
        Capabilities: [dc] Power Management version 1
        Kernel driver in use: EMU10K1_Audigy



The last line is what you look for.  If you see something like that then
it could be as simple as the sound is muted.  I have no idea why but as
a general rule, the sound is muted when you install.  I use KDE so I had
to unmute with Kmix and alsamixer to get mine working. 

If it doesn't show a driver in use, then you have to either build a
module or a new kernel if you want it built in.  In that case, let us
know what kind of sound card you have.  The output from lspci would be
great.

Here is lshw info

and lspci

00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High

        Kernel driver in use: HDA Intel

I did built the sound support into the kernel.

I run a lean gentoo install; no desktop; only a window manager
(windowmaker). Nothing related to alsa is installed. I installed adobe's
flash player plugin which ended up in ~/.mozilla/plugins/libflashplayer.so

When I play a flash video I don't see an option for turning on audio.

Looks like you've got it installed properly... have you unmuted the
sound? AFAIK alsa mutes everything by default. Run alsamixer and play
a video with sound and adjust them until you hear something.

At least you are past the kernel part and know the hardware should be
working.  I had to install alsamixergui to unmute mine.  Since I have a
somewhat bloated install, I'm not sure how you would unmute yours.  You
may have to install some kind of alsa to do that.  I'm not really sure
in this situation.

Here is a link about alsa:

http://www.alsa-project.org/main/index.php/Matrix:Module-intel8x0

I read in there that cards are muted by default.  It says it this way: 
"Now adjust your soundcard's volume levels. All mixer channels are muted
by default. You must use a native mixer program to unmute appropriate
channels, for example alsamixer from the alsa-utils package."   I would
do a emerge -p alsa-utils and just see if it is going to try to install
the kitchen sink or just it and perhaps a couple others that you can
live with.

That help?

I think I am getting close. My video player is vlc and I reemerged with
alsa support; that pulled only the relevant alsa packages. Then
downloaded a flv video and played; no sound. But got some clue.

Will follow the gentoo online doc on alsa to troubleshoot. Seems I will

First off - do you have PulseAudio running? If so, for HW/ALSA testing
purposes, shut it down. Second, check your mixer settings to determine if
your volume levels are appropriate. A great quick CLI app for this is
alsamixer (media-sound/alsa-utils) - first start the alsasound service (sudo
/etc/init.d/alsasound start), then run alsamixer - set your volumes to about
80%, and unmute all channels (use the 'm' key to toggle mute), then restart
the alsasound service to save your volume levels (sudo /etc/init.d/alsasound
restart), then add the alsasound service to your boot runlevel (sudo
rc-update add alsasound boot). This will set it up to restore these volume
levels on every startup (it will also save your *current* volume levels on
every shutdown, so don't mute, shutdown, and expect to be unmuted after
starting back up).

Now, double-check that PulseAudio is not running (ps -elf | grep -i pulse),
and kill it if it is.

Then run:

aplay /usr/share/sounds/alsa/Front_Center.wav

If you hear sound - great, ALSA and your sound HW are working, and Flash
audio will almost certainly start magically working. If not, please post the
output of:

aplay -l
aplay -L

(both of those are L, first one lower case, second upper)

HTH-

Try to enable the alsasound service (as root):

   rc-config add alsasound default

To start it without having to reboot:

   /etc/init.d/alsasound start

Restart X and try again.

You haven't made it clear - in any of your subsequent posts, either -  
if sound is working for other applications.

If you get a new email, does your laptop go "bing!"? Can you play an  
MP3 by double clicking on it or at the command line? What if you run  
mplayer at the command line on an AVI video?

If you have only previously used your laptop for email, surfing the  
web or writing code, it's not clear that sound may *ever* have been  
working on it. IMO you need to get sound working for a basic program  
that uses audio before worrying about Flash, which seems more  
problematic.

I have never configured sound. It has never worked.

No sound.

Indeed this is the case and I am trying to get it to work since some
tutorials I need to listen to are only available on video with audio.

 After rebuilding the kernel with additional intel driver support and
adding users to the audio group, sound was enabled.

Thanks for the help.
