View Full Version : [SOLVED] Sound? OFF! - Yes, no sound.

August 24th, 2009, 04:23 AM
Been working on a sound problem, as I am new to welcoming Linux. Followed a lot of guides and so far no luck. Sound is HDMI from card1 on an integrated motherboard. (card 1 is HDMI ; card 0 is normal sound through sound jacks?)

Here is the oddities of the problem:
When I boot up and when loading screen appears, I believe I have sound as my audio receiver is picking up a signal (via HDMI). Once the desktop appears, sound signal is lost. I can test the sound card and I hear a tone, which makes me believe sound is working or at least a connection is established. I can use rythmbox and hear sound through that. Any other application, and no sound at all. IF I manually select an audio driver in an application (SMPLAYER), I can get sound although video quality is a bit subpar.

Here is what I think is happening, and maybe someone can concur. Whenever the desktop is loaded after booting, somehow card 0 is being loaded instead of card 1. When I manually tell an application what to use, such as guiding the application to use a sound driver, is when sound works.

If my assumption is correct on the sound problem, is there anyway to disable the system from loading card 0 and making card 1 the default sound source? If so, HOW? IF this is not my problem, what is my problem and how do I correct?

Thank you

yes there is but you need to tell us what operating system you are using

August 24th, 2009, 04:52 PM
The os is ubuntu 9.04

Do you have a volume control icon in your task bar? If so, double-click it and check the sliders. If not, right-click the task bar and add one.

If the problem is only playing .mp3 / no sound in youtube clips, it's a missing codec problem. I have a hard time believing the installer wouldn't get flash-nonfree for your browser automatically, but if so get it with Synaptic.

For mp3 I just double-clicked an mp3 file and my media player (totem) got the nonfree codecs "automatically".

August 24th, 2009, 05:26 PM
No system sounds are played either. Don,t think it's a codec issue. Tried all the slider tricks in volume control to no avail.

I guess I may not be the only one stumped on this?
Cresho may have had a resolution for this....?!

open up terminal


tell us what it says about your card, chip.

now use your tab key and select all.

use your arrow keys and look for

you can select a volume with the arrow keys left or right. if you choose a volume, use up and down keys to change levels.

What i need you to look for is something that actually turns on your audio. I have a few fixes up my sleeve but i need to know in general what is supported.

on my system for example, i select "audigy A" switch (light-on green indicates on) which i have on. above in item it says analog digital output jack. this is the type of switch i am wondering if you have on your system. is it analog/digital off or on?

after we resolve this or if it gets resolved, I can tell your system to force boot and resolve any issues.

If my assumption is correct on the sound problem, is there anyway to disable the system from loading card 0 and making card 1 the default sound source? If so, HOW?
Is there an option in the computer's BIOS to disable card 0 and make card 1 the default sound source? If so, then try that.

could be an audio priority but we can get to that after. I need to see if his mixer sees the unit like the post i made right above yours as I mentioned.

August 27th, 2009, 11:27 PM
Out of town at the moment, but from what I remember is that nothing was muted (if that is what you are referring to?). I did alsamixer card0 and card1 and all sound options are active (green light). I figured they were not muted as I can get sound on some applications when I reference the audio driver.
It may be the audio priority you mention Cresho. What are your thoughts on how to set the priority? I only know of blacklisting card 0, which didn't work.

August 31st, 2009, 12:48 AM
It doesnt matter if its muted or not, there is a switch that tells your card to go on. This is what I am looking for. I'm starting simple and then we go for the harder stuff.

August 31st, 2009, 03:31 AM
ok. Typed alsamixer and came up with:
chip: ATI ATI RS690/780 HDMI
View: [ALL]
Item: IEC958

Only one box at the bottom with two zeros with green background. Can't do anything with it (up, down arrow, etc).

I open rhythmbox and can hear sound ; smplayer with ATI HDMI selected for audio driver and have sound. Everything else, no sound.

Is there anything else I should do?

one thing you may want to watch out for is in the audio mixer there is sometimes a resource that can be toggled to switch between analog out or digitial out.

I experianced this on my laptop and my desktop ( sound blaster audigy2 ) the default for the setting should always be analog but what happens is sometimes it comes up digital out and that effectively shuts off any normal analog sound hence " no sound " unless connected with digital to a digital reciever.

just go into the mixer with the appropiate device selected and look in preferences for anything labeled analog/digital output jack. If it is not checked check it then go into the mixer under the switches tab and you can then toggle it to see if that helps.

just like the guy above says.

anyway, do a

#asoundconf list

in the terminal and tell me what you see? we may need to force boot the correct sound device which is not hard. I just need to see this command output im asking for.

Took me a while...realized when I played with this last night, I blacklisted a few items and result was nothing when I typed asoundconf list

Here are the results after deleting my added items to blacklist.

Names of available sound cards:

im going to assume you are using hardy.

install this one

if you want to try a gui use this one
#sudo apt-get install asoundconf-gtk

then you can select your soundcard in

system->preferences->default sound card

you select that and select the audio you want to try. now you play with your audio mixer and software to see whats going on.

if you dont want to play with a gui, you can do it in terminal like for example you have checked for your audio.

#asoundconf list

choose one audio and execute this

asoundconf set-default-card SB


asoundconf set-default-card HDMI

if you create a script, you can do this and place it in sessions to force your card as primary.

sleep 10 && asoundconf set-default-card HDMI;

select one card and play with mixer and audio. if not, try other card and repeat your process.

if this isnt working, you will definetly need to check the audio hardware. What is it?

got sound when testing via GUI by selecting the HDMI device. Sound was clear. asoundconf set-default-card HDMI did not work apparently.

Same situation as earlier though. no applications have sound except rhythmbox and smplayer when I select the audio driver.

Re-installed the whole OS. nothing. seems worse than before.

I just had the exact same issuie today, it took me a long time to figure out. it sounds like you've got 2 sound chips (I had 3...yeah, I'm crazy). There's an elegant way to do this - simply disable the default sound card and the HDMI one becomes the primary sound chip by default.

open your terminal and type

sudo lsmod | less

Near the bottom of the list, you should see a few lines beginning with "snd_" - those are your sound chips. I had things like "Snd_intel8x0" and "snd_emu01k." The sound card you want to use (the one you're not disabling) should have ATI somewhere in its name. Copy the ID of the other sound card (the one you're disabling), or write it down somewhere.

Open your file browser and go to /etc/modprobe.d/ and open the "blacklist" file (I had to open it with sudo). At the end of the file, add these lines:

#Disable the analog soundcard
blacklist (soundcard ID)

Once you reboot, your HDMI sound chip will be default, since it's the only sound chip enabled. Enjoy the sound :popcorn:

I think this is the route I need to go, rockbuster. Here is what I got from aplay -l
card 0: SB [HDA ATI SB], device 0: ALC1200 Analog [ALC1200 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 0: SB [HDA ATI SB], device 1: ALC1200 Digital [ALC1200 Digital]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 1: HDMI [HDA ATI HDMI], device 3: ATI HDMI [ATI HDMI]
Subdevices: 1/1
Subdevice #0: subdevice #0

This is what I got from your lsmod | less (edited):
snd_hda_intel 435636 3
snd_pcm_oss 46336 0
snd_mixer_oss 22656 1 snd_pcm_oss
snd_pcm 82948 2 snd_hda_intel,snd_pcm_oss

Nothing that appears to be too detailed like you describe. Anyway to blacklist card0?

SO....I have given up on this for now. After a few more alterations, I finally got NO SOUND AT ALL. Not even during tests. I haven't even started on my hauppauge 1800 tvtuner card (what's the point if I don't have sound). I think I may upgrade to 9.10 and see what happens. I just don't understand why this is so difficult. So far, I haven't gotten to
"linux just works"

As a person who wanted to explore linux via UBUNTU, this is not a good start.

I do want to thank everyone so far for their help.

November 14th, 2009, 01:58 AM
SO....9.10 works for sound coming through "normal" sound speakers (i.e. not hooked up to HDMI routed to a receiver). This is one BIG improvement than earlier.

January 6th, 2010, 01:04 AM
Finally got around to hooking up HDMI to my surround sound system. Works great. Looks like 9.10 did the trick.
