[SOLVED] sound in flash not working for me Slackware 64 14.0

emgee_1 · 10-03-2012, 02:52 AM

Dear slackers,

Sound in flash is not working for me.
I installed full slackware64 14.0
I installed flash plugin from SBo git current.

Sound in kde phonon (test) works.
Ted videos in chromium (installed using Slackwiki) start playing with sound but stop after some 10 -20 seconds.

I did a # alsactl init
All flash video have no sound
A cd plays ok with sound

Using xfce and installed mixer plugin showing 3 cards(?)

Code:

lsmod | grep snd

#alsacntl init

Code:

alsactl init
Found hardware: "HDA-Intel" "ATI R6xx HDMI" "HDA:1002aa01,00aa0100,00100200" "0x1025" "0x059f"
Hardware is initialized using a generic method

Any idea I could try otherwise?

I made also a file in /etc/modprobe.d named sound.conf containing

Code:

options snd-hda-intel model=auto

to no avail.

Any ideas are welcome!

Thank you

I had a similar problem. Run "aplay -l" which should give you a list of available devices and subdevices.

I found a file /etc/asound.conf (of which I do not know who created it...) and there the entries defaults.pcm.ctl.card and defaults.pcm.card are followed by defaults.pcm.device and defaults.pcm.subdevice. Checking these with the output of aplay -l showed that the device and subdevice numbers were not the correct ones, which leads to a failure of "pure alsa". (I hope to remember these thing correctly. In the present machine which is always updated to current, I have no /etc/asound.conf. So, this is from memory...)

Phonon in KDE chooses the devices directly, and therefore does not rely on that mechanism. Which is why the KDE apps work alright.

Obviously, this is just a possibility. But in the fresh install we had exactly these problems...

Good luck

This is what I experienced with 13.37 and found a solution, I do not remember where

Create a text file .asoundrc in your account and copy-paste following in it:

pcm.!default {
type hw
card 0
}

ctl.!default {
type hw
card 0
}

If it's a laptop, can it be the speakers don't work, but if you plug in a pair of headphones those work?

I'm saying this because there's a kernel bug around that mute internal speakers that seems fixed in yesterday kernel updates...
And I say "seems" because I'm affected too by this bug but I've not yet time to try the new kernel releases.

EDIT: just FYI, I have the speakers muted on this laptop also with the latest kernels

the bug is described here

emgee_1 · 10-04-2012, 03:29 AM

@ponce : It is indeed a laptop but your suggestions did not change a thing unfortunately
@grave_violin : I created the file .asoundrc in my home dir /home/mg but no sound either unfortunately
@ fsauer : your suggestion looks promising but I do no know how to exactly to implement it:

aplay -l gives

Code:

aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 1: Generic_1 [HD-Audio Generic], device 0: ALC269VB Analog [ALC269VB Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

I did not have an asound.conf in /etc

I found :

Code:

bash-4.2# cd /etc
bash-4.2# ls -R | grep asound
asound.state

which contains

This looks to me the settings of my mixer widget in xfce4
I guess I have to create some config file that gives the correct order of the devices but do not yet know how. I guess that it has to do with udev and the way first sound devices are recognized.

Maybe I should try another kernel?
I know that sound worked under sabayon 9 on this laptop which I exchanged gladly for slackware 14.

Any ideas suggestions are much appreciated.

fsauer · 10-05-2012, 03:40 AM

I found out that my son had created the /etc/asound.conf before I used it. This explains why I didn't know where it came from.

He created it after reading:
https://wiki.archlinux.org/index.php...ult_sound_card

Maybe the .asoundrc (see post by grave_violin) could be useful for you. As your card 0 is the hdmi one, you should modify the .asoundrc accordingly ("card 1" instead of "card 0").
As you use the default device 0 anyways, this should be ok.

If you want to use the HDMI sound, you have to configure card 0, device 3 subdevice 0, which is exactly what we had to do

Good luck!

emgee_1 · 10-05-2012, 06:30 AM

Dear fsauer and others, who helped me. It turns indeed out that the solution provided by fsauer is indeed the correct one.

I will take some time to write down the different steps that were tried and finally lead to the solution. Then maybe an entry at the doc project. At least since rc3 or Slackware 14 rc4 we have had no sound.
This is great if your kids are playing games on your laptop but in the end quite annoying. Thank YOU

im having an internet problem, i cant figure out how to buy grave_violin a beer for that answer, thank you a lot either way.

I think you need to buy one for fsauer also.

ahzthecat · 06-21-2013, 12:43 AM

Sorry to resurrect this old thread, but I'm having a similar problem and the advice here only gets me halfway solved.

I'm using Slackware64-current KDE on an Acer aspire, trying to get HDMI to work when attached but for the system to default to analog when HDMI is not connected.

I have succeeded in setting HDMI as default with /.asoundrc, but that renders analog sound unuseable. There must be a way to have both working properly, but I can't seem to figure it out.

here's the output of aplay -l

Code:

**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC271X Analog [ALC271X Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

and here's my /.asoundrc

Code:

pcm.!default {
    type hw
    card 0
    device 3
}
ctl.!default {
    type hw
    card 0
    device 0
}

As I said, this setup gives me HDMI only. How can I jigger this to use HDMI when available and analog when no HDMI is available?

Thanks for any ideas!

number22 · 06-21-2013, 02:23 AM

you can use alsa plugin dmix, route, or multi
google combine multiple streams from multiple sound card for alsa. although, you need create dummy control device.
example multi from:
http://jackaudio.org/multiple_devices

Code:

pcm.merge {
    type multi;
    slaves.a.pcm hw:0
    slaves.a.channels 2;
    slaves.b.pcm hw:1
    slaves.b.channels 2;
    bindings.0.slave a;
    bindings.0.channel 0;
    bindings.1.slave b;
    bindings.1.channel 0;
    bindings.2.slave a;
    bindings.2.channel 1;
    bindings.3.slave b;
    bindings.3.channel 1;
}
ctl.merge {
    type hw
    card 0
}

Looking more closely, is it odd that hdmi and analog are both listed as Card 0 in my aplay output?
