Failing to get sound to work

#1 Post by Mwphoto »

This is a newbie request for help setting up my sound drivers, I apologise if I've posted to the wrong forum . . .

I've got the pupp 1.0.2RC (that may be my problem straight away ;)

I'm setting up the system and I have video, LAN with no problems, however I have no sound . . .

First some specs:
Motherboard is ASUS a7v400 with everything integrated (VIA chips)

Result of the hardware probe is shown below

===== query_pci_devices =====

1106:b198 (6,4) 0 [ (null) - (null) ] BRIDGE (null)
1106:3205 (6,0) 0 [ (null) - (null) ] BRIDGE (null)

The problem is I get no sound, every app seems to work (ie I don't get fatal errors when I run them) but I get nothing from the speakers. I know the cabling/amp/vol are all ok as I can reboot the system into windows without touching anything and I get plenty of sounds.

one thing that looks suspicious to me is that XTmix does not have a green light over the wave device (I don't understand xtmix - is the light for recording?)

mixer volume and overall volume are set to about 75% in xtmix

While I'm windows literate (I program for a living) I don't know linux so if you're replying assume reasonable intelligence but little knowledge :)

Many thanks

Have you looked at the previous post in this section on sound cards.
It might or might not help you.

In Puppy 1.0.2 if you have a via sound chip

go to /etc/rc.d/rc.local

edit it to include

modprobe via82cxxx-audio

Do we have more codes available for different sound configs we can put on the wiki?

Guys,

thanks for the replies, I did the modprobe via etc and no luck, it seems to me that the drivers are all in place. Is there any log file or equivalent I can look for that might tell me if an error has been encountered?

solution found!!!

Guys,

It was a cabling problem after all :oops: In the windows environment I was configured for 6 channel audio so I was getting an audio signal from the 3 jack connections.

For puppy I think I'm configured for standard 2 channel output, and that meant there was no signal on the channel the speakers were plugged into!

mmc

can u elaborate?

Hi malcolm,

Could you elaborate on how u fixed up ur cabling problem? I dont quite understand (where did you find the two channel configuration)

I was also not getting any sound (works in windows though), however, i am able to view videos

Actually i have the same audio card as yours, viatechnolgy ac97 (and same id) and i am using release 1.02

These are some of the error reports .....
# xtmix
xtmix: Error opening mixer device /dev/mixer
FATAL: /dev/mixer probably does not exist or has no r/w permissions

This was the log file from snack audio player when trying to play a mp3 file

/begin
Could not gain access to /dev/sound/dsp for writing.
Could not gain access to /dev/sound/dsp for writing.
while executing
"s play -command Next"
(procedure "Play" line 13)
invoked from within
"Play"
invoked from within
".panel.bp invoke"
("uplevel" body line 1)
invoked from within
"uplevel #0 [list $w invoke]"
(procedure "tk::ButtonUp" line 22)
invoked from within
"tk::ButtonUp .panel.bp"
(command bound to event)

/end

I found that /dev/dsp exists but /dev/sound did not, so i did a mkdir sound; cd sound; mkdir dsp; chmod -r 777 /dev/sound/dsp. with no success

meanwhile i am not able to open the audio control panel either by double clicking, left/ right/middle clicking, it however resides in the systray, and i dont see any green light with 75 % you mentioned

i apologize if this is a dumb newbie question

Thanks

Audio is working now

I feel so silly that i missed out the excellent contextual help that comes with hardware probe tool. I later found my solution from this thread

http://www.murga.org/%7Epuppy/viewtopic.php?t=155
Well, Puppy responds to his master's voice. The audio began working after the following steps:

TEST SEQUENCE
Boot
Test MP3 CD in MPlayer - no sound
run # lsmod - no audio drivers shown loaded
run # modprobe via82cxxx_audio
Test MP3 CD in MPlayer - sound now working
run # lsmod again - now shows via82cxxx loaded
It just works off the bat

actually lobster pointed to it right away, but i think that there was a typo namely it should be via82cxxx_audio instead of via82cxxx-audio
