No Sound Web Browser (other apps ok) [Solved]

[hal8000]

I'm using PCLiuxOS 2011.09 ISO all updated.

I have no sound using Firefox or Chromium. All other sounds KDE , vlc, mplayer etc work.
Main sound card is built into my Gigabyte motherboard and uses the snd_hda_intel driver.
However my graphics card is an ATI 5770 with HDMI Audio and I'm  sure all sound from the web browser is being directed to the HDMI port.

So far, I've enabled and disabled pulse audio, changed output device preferences in Phonon and edited /etc/modprobe.conf  as per this post by Tex:

http://www.pclinuxos.com/forum/index.php/topic,66982.0.html


So far all my efforts have failed to create sound. I'm using iPlayer for reference.
Some hardware details:

I have not yet tried an alternate desktop (to see if its just related to KDE) but open to suggestions,
thanks in advance.

I>'m having the same issue with a Radeon HD 4700 and an Abit KN8 Ultra v1.1 mobo (which is what I always use for sound).  I tried >Texstar's trick from the thread referenced above.

output from lspcidrake -v | fgrep -i AUDIO was

As a side note, avoid Rosewill RK101 PS/2 keyboards.  In linux, holding down the left shift key causes extra "greater than" characters to be inserted into input, very distressing when entering passwords.

I am experiencing alternative block-outs:

If I play sound in browser there's no sound in some players.

If I play sound in a player there's no sound in some browsers.

Since that some is not general I still can find the sound in both cases.

-------------------
But there's some problem I think. May be PulseAudio<->Alsa discrepancies?

[Just17]

hal8000,
                with Pulse Audio installed and working, launch (install if necessary) pavucontrol.
On its configuration tab select the HDMI drop-down list and disable the HDMI.

All sounds should now be directed elsewhere.

If you wish to leave it enabled for some uses ......  say a particular application which you use to play video put the HDMI port, then on the Playback tab, with an app playing a sound you cannot hear, select the drop-down for that app and direct the sound stream to other than the HDMI port.

It works very well here.

All settings are remembered on a per-application basis.

Just18,
pulseaudio worked for me.  I may disable amplification, cos stuff is REALLY loud.

Try using the sliders in pavucontrol to set things ......  or maybe the sliders in Kmix might suffice ......  launch the mixer.

Glad to know it helped with your problem

Hi Just18, I think your solution may work for me, but now I have a new problem pavucontrol does not start - says connection refused. A quick google and I see I am not alone with this error either.

If I start the terminal in KDE, and try pulse-audio I get

[anc@orac $ pulseaudio
E: main.c: Daemon startup without any loaded modules, refusing to work.


So now I know no pulse audio hasn't loaded modules.
If I try pulse-enable:

[anc@orac ]$ pulse-enable
update-alternatives: unable to open /var/lib/rpm/alternatives/soundprofile.rpm-new for write: Permission denied
update-alternatives: unable to open /var/lib/rpm/alternatives/soundprofile.rpm-new for write: Permission denied
update-alternatives: unable to open /var/lib/rpm/alternatives/soundprofile.rpm-new for write: Permission denied
Can't remove /etc/sysconfig/pulseaudio: Permission denied, skipping file.
Pulse Audio has been enabled. Please reboot your system now.

If I cd to   /var/lib/rpm/alternatives

I only have 1 file, soundprofile, not soundprofile.rpm-new.
I may try creating the file manually, but for now the contents of soundprofile are below:

cat soundprofile
auto
/etc/sound/profiles/current

/etc/sound/profiles/pulse
20


Not sure if 20 is referring to the script order.
Wonder if you could post me contents of your
soundprofile and soundprofile.rpm-new

file if they are on your system. Sound is working, just the annoying no sound from browser
which is redirected to HDMI audio.
Thanks for your help so far.



/etc/sound/profiles/pulse
20

Hi Just18, I think your solution may work for me, but now I have a new problem pavucontrol does not start - says connection refused.

First of all make sure that you have installed PulseAudio using the meta package in the repo .....  task-pulseaudio in Synaptic.

The only time this has happened here is when PulseAudio is not running ......  so the connection cannot be made.

I think if you approach the problem from that angle you may solve it ......  maybe initially turn it off in PCC and reboot, then turn it on again in PCC and reboot.
Do NOT do anything before those reboots.
When turning on/off PA ensure you have no apps running.

After rebooting with PA turned on again, try launching pavucontrol.

If this does not work then I suggest you remove PA (task-pulseaudio-remove), reboot, and reinstall and turn it on, then reboot again.

regards.

[anc@orac ]$ pulse-enable

I would imagine you need to be root for this ..... hence permission denied

Hi Just18,
Thanks for all your help. I did not have task-pulseaudio installed.
Removed all , rebooted reinstalled and now sound works, thank
you for the support.

Glad you got it sorted

Just18, Thanks for the Pulse Audio tip. I am dual booting Win7 and PCLOS on my new Acer Aspire 5560G and had the same no Firefox or Clementine Sound and crippled Kmixer. I got Clementine going by changing the output settings in Clementine but only your tip on installing, enabling, pulses audio, then unenabling and removing Pulse audio via KCC and Syanaptic then all back in again fixed it all. Settings in Pulse audio needed tweaking by setting the capture to monitor of analog speakers vs analog speakers. It also took me a while to figure out a program, like Audacity,  had to be running before Pulse audio would see a recording stream.  Now as far as I can tell, this Laptop is 100% functional in PCLOS. 

Off topic, PCLOS 2012.4 did not initially recognize the Broadcom wifi but the very first update fixed it.
Thanks guys

[Just17]

Glad it helped cpufrier

There are also a lot of other functions available in PulseAudio, such as
recording
loopback mixing
sending & receiving audio on the LAN
etc

For some items there are extra pulseaudio-modules to be installed, while for others the functions are there but you may have to discover them.


I have posted some of my musings, while trying to understand PulseAudio in this thread ...

http://www.pclinuxos.com/forum/index.php/topic,105160.0.html

You may find something of interest ...... for instance I posted a (very very simple) PA-recording script which allows you to record from any device that PA can handle.
