Default Re: GT430 On Linux (Slackware64 13.1) not recognized by ALSA

OK if I understand correctly, there is 2 different roads I can take to solve this problem...

1. Patch alsa using http://git.alsa-project.org/?p=alsa-...dd4916121a4f6a
or
2. use the probe_mask approach

Having absolutely no experience with these patches, I decided to give the probe_mask solution a try. I followed the instructions of http://wiki.xbmc.org/?title=HOW-TO_s...20%2C_or_GT240 but it seems not to work.

In a nutshell, heres what I did:

-Created /etc/modprobe.d/sound.conf because it was non existent
-Added
Code:
options snd-hda-intel enable_msi=0 probe_mask=0x108
to the file above (0x108 is from your instructions because eld#3.0 has my TV info.)
-Rebooted

Everything complains of no audio device, no sound, alsa problems, etc

vlc says
Code:
Potential ALSA version problem:
VLC failed to initialize your sound output device (if any).
Please update alsa-lib to version 1.0.23-2-g8d80d5f or higher to try to fix this issue.
mplayer says
Code:
[AO_ALSA] Playback open error: No such file or directory
Failed to initialize audio driver 'alsa'
Could not open/initialize audio device -> no sound.
Audio: no sound
Plus I have no sound in flash, amarok, anywhere in the system...Even KDE sounds are not working. Overall its a mess...........

I have the same card and distro although i am running current.

I have managed to almost get everything to work, i can now get sound through KDE and the KDE apps, also i can get VLC to work by selecting the card directly in the sound options but mplayer complains of no sound card and flash does not work.

To get sound in KDE go to system settings and then multimedia and on the phonon tab there is the option to set the preferred card.

Alsamixer is showing volume controls for the hdmi but as above i cannot get all apps to use it by default. Can you confirm that i just need to patch alsa or am i missing something else?

I have tried kernel 2.6.37 and 2.6.8-rc2 btw.


Edit

I have resolved my issues by creating a ~/.asoundrc file with the following

Quote:
pcm.!default {
type hw
card 0
device 9
}
ctl.!default {
type hw
card 0
device 9
}

hey savo! thanks for your feedback

talking about sound in KDE, I really dont know why, after the modifications with the mask probe I did last time, I am randomly getting kde to output sound thru hdmi... last time I wrote here on this thread, the sound did not work. Now, as I am writing this message, it works. I guess it is intermittent... probably some settings not correct. TO be honest, I have no clue of what I am doing. Alsa and sound in linux seems pretty complicated.

Yeah when I opened this window, kde tasked me what I want to do with devices that were apparently no longer available. The list was extensive with many "cards" I previously had working. THis includes all ATI based cards (on the mobo).

attached is a screenshot of the kde applet. Look at it and tell me what you think.

I also opened kmix and noticed everything is gone... except one IEC958 device under theHDA NVIDIA... I remember to have seen at least 4 IEC devices there last time...

What does the asoundrc file really do?

My ultimate goal is to have the Hdmi sound from my gt430 videocard working perfectly until I buy speakers and hook them with the optical spdif port from the integrated ati sound chipset. Then, the hdmi sound will be disabled (or whatever).

OK I ditched KDE alltogether because I had too many troubles with it...And considering my sound issues are far from over so I need to repost here.

Like I said, I am now using XFCE. because stephen warren suggested to de-activate the onboard sound controller (ATI) I did. now, aplay -l gives:

Code:
bash-4.1# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: NVidia [HDA NVidia], device 3: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 7: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 8: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 9: HDMI 0 [HDMI 0]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
I have NO .asoundrc & NO /etc/modprobe.d/sound.conf files...

I tried to test the card with

Code:
speaker-test -c 2 -r 48000 -D hw:X,Y
But for X,Y, none of 0,3 0,7 0,8 0,9 will output test sound... They all seem to run without issues as I dont see errors in the terminal but I cant hear the white noise...

MPlayer (both gmplayer & the terminal version) are saying

Code:
AO_ALSA: Mixer attach default error: Invalid argument
. The box is totally mute. Cant get sound anywhere...

I dont get it.

Any help appreciated...

thanks!

Seems that creating a $HOME/.asoundrc file with

Code:
pcm.!default {
type hw
card 0
device 3
}
ctl.!default {
type hw
card 0
device 3
}
adding a file nvidia-hdmi.conf in /etc/modprobe.d/ with

Code:
options snd-hda-intel enable_msi=0 probe_mask=0x108
Did it! I am getting sound from every applications, even youtube and other flash sites.

When I buy a nice set of speakers, I will redo all this to use the optical output of the mainboard. Will see then!

Thanks guys!
