Title: OSS or Alsa doesn't recognize my audio HW, HP PavillionG7 Laptop
Post by: enoch on July 24, 2013, 06:55:14 AM

Usually the sound in one of the easiest things to get working, however on this laptop
its a challenge, the sound is SRS Premium with Altec Lansing speakers. Any help is much
appreciated.

I tried the Alsa files, just won't see the audio, there is something unique about this laptop.

Perhaps post the results of LSPCI  then maybe someone who has the same audio chipset can help

Did you follow the instructions in the alsa extension info file?

What happens when you try the following:

Code: [Select]

$ sudo /usr/local/etc/init.d/alsasound start

You need to use either alsa or oss, but not both.

If you get "then Starting sound driver : snd-hda-intel" after the "..alsasound start" command, it looks like your sound hardware will work.

I suggest you reboot,  load only the alsa extensions and try again.

I'm assuming you meant:

1. reboot
2. load alsa extensions
3. sudo /usr/local/etc/init.d/alsasound start
4. check alsamixer to see that sound is not muted

..and still no joy?

I had problems with the sound on a macmini with intel hardware and got things working with hda analyzer (search the forums for this).

The good news is that the macmini sound works without hacking with tc-5.x...

yes those are the last steps implemented

when I launch xmms, it shows a song playing, then click on the play button yields thus
Your soundcard is not con figured properly
You have the correct plugin selected
No other program is blocking the soundcard

Do you hear sound with speaker-test?

Post by: enoch on July 27, 2013, 11:28:47 AM

No sound here is the result

tc@box:~$ speaker-test

While no sound with speaker-test playing with xmmx and etc. are just time wasting.

How about:

Code: [Select]

$ speaker-test -c2 -t wav -l1

I think that means you are trying to play through  card2  and it does not exist or can't be found.
Googling   ALSA lib pcm_dmix.c:1018:(snd_pcm_dmix_open) unable to open slave
turned up:

See which cards are listed in  /proc/asound  and try setting up a  .asoundrc  in your home directory. Then restart alsa.
