PostPosted: Tue 17 May 2005, 06:05    Post_subject:  Failing to get sound to work  

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 Wink

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 =====
10de: 172 (3,0) 0 [ (null) - (null) ] (null)

1106:3104 (12,3) 11 [ VIA Technologies - ] USB ehci-hcd
1106:3038 (12,3) 11 [ VIA Technologies - VT 82C586B Apollo ] USB usb-uhci

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 Smile

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?

PostPosted: Tue 17 May 2005, 09:57    Post_subject: solution found!!!  

Guys,

It was a cabling problem after all Embarassed 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!

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

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

Quote:
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
