Aspire 722 audio missing

OdinEidolon · 2011-11-02 20:20:33

Hi all, I have no audio in a recently installed Arch on an Aspire 722. Not a note from the speakers nor from the headphone jack.
I have read tens of topics but all seem to say that audio works out of the box, except for headphones, but in my case it doesn't.

This is what I read:

and of course:

None helped, but I didn't get much of it honestly.

I can provide whatever info needed.
Some codes:

Now for some reason audio works in kde test page (phonon) but not anywhere else (youtube, smplayer...)

The output from aplay -l above shows that you have two sound adapters on that laptop.

Card 0, Device 3, is the HDMI output sound device;

Card 1, Device 0, is the analog output device (your speakers);

and the output from that ls command shows that the microphone is on Card 1, Device 0 (pcmC1D0c... "c" means "capture", while a "p" would mean "playback").

So, which device are you using for your testing?

From looking at the output of that speaker-test command, my guess is you're sending the sound to the HDMI ouput.

Try specifically using the analog device... something like the following:

speaker-test -c 2 -D plughw:1,0

which will send a test signal to Card 1, Device 0.

If that happens to work, then go back to that Arch wiki page about ALSA that you mentioned in comment #1 and see Section 3.1 about setting up a "default" ALSA device if you don't want to tell all your sound applications which ALSA device to use.

Also, sometimes the Card numbers can swap after a reboot when there are multiple sound adapters installed, so first run that aplay -l command before trying the test to verify the current setup. See that same Section on the Arch wiki page to prevent this swapping of Card numbers by using /etc/modprobe.d/alsa.conf.

Thanks for your reply. Sadly I do not have the said netbook available until weekend, but I can state what I can remember. Testing, as I should of course have stated before (sorry!) returned positive result only when using what KDE called "default", "(something like) ATI HD (not HDMI)" and "hw 1:0". Other audio devices did not work. I may be wrong tho.

Will do. I'll ask my mother if she can do it and if so I'll post the results. If not I'll do it on friday.

Thanks again.

Hi. Sorry I'm late.

Speaker test returns:

 Playback open error: -16,Dispositivo o risorsa occupata

Which is "device or resource busy".

Phonon testing: works under "HDA ATI SB (CONEXANT Analog)"; "default"; "hw:0,1"
does not work under: "hw:0,3"; "HD-Audio Generic, HDMI 0 (HDMI Audio Output)"; "HDA ATI SB, CONEXANT Analog (Default Audio Device)" (this last one is nt even selectable).

Sounds to me KDE is locking the audio channel?

Logged out of KDE and started the speker test again - it works!
So the problem is KDE locking the audio for himself?
