Sound on AMD Geode LX800

[s3704ssv]

hello to all!,

I am having problems with getting alsa working on my AMD Geode Device!, no audio output at all  .

alsamixer displays:
Card: CS5535 Audio
Chip: 0x800f800f P¦P  <-- not properly detected???

I'm seeing plenty of error like [in dmesg]:
May 19 04:17:25 (none) user.err kernel: Failure writing to cs5535 codec
May 19 04:17:25 (none) user.err kernel: Failure reading codec reg 0x7c,Last value=0x2680800f

Please see attached files

I hope someone can help out!

isapnp off

and you can test it with the sb16 driver...

Perhabs.. there are lot of problems with the Geode moduls..

@wohlstandpenner

I have tried out the boot code isapnp=off and tried to load alsa.tcz and still no avail

how to load these sound blaster modules? like 'sudo modprobe sb16'

note: I have tried this unit of mine on windows xp and ubuntu 8.10 and the sound works!

[wohlstandpenner]

looks on ubuntu whats configure you have..for sound..

I have some geode clients from the geode gx to geode lx..
It was very diificult to run sound on this device with tinycore.. But i have bring it to work..
Oss run often better on this devices.. I searched when i come home, for the modprobe modules parameters

@^thehatsrule^

My apologies, I thought it was the right section to post. Anyways, Thank You.

@wohlstandpenner

ubuntu 8,10 loading on an AMD Geode LX800 is too slow too boot  and I don't know what to search for in order to import/note its settings.

@all

Any info would be appreciated!

I have tried using OSS and it works out of the box 

Can somebody tell the difference or enlighten me about OSS and ALSA? I'll be just playing wav, mp3, ogg or other audio files [maybe 2 to 3 players running the same time].

Will OSS be enough for my needs as indicated above?

[curaga]

Different sound systems, both with pros and cons, that's all. For a bit OSS-biased history see
http://insanecoding.blogspot.com/2007/05/sorry-state-of-sound-in-linux.html

OSS can handle your use case just fine.

[s3704ssv]

ok, but I seem to be deviating to my topic titile

anyways, lets say I'll use OSS instead.

I've already loaded OSS.tcz and tested it with osstest and there was sound output!

[loaded up mpg321.tcz, ogg-vorbis.tcz and oggz.tcz as well]
I have 3 audio samples: 1 wav, 1 ogg and 1 mp3

played them in ossplay and only the wav file is played

played them in mpg321 and only the mp3 file is played [the wav file seems garbage and the ogg file did not play]

what audio plugins that I'm missing?

AND I seem can't do simultaneous playing

these are what ossdevlinks says:

what audio plugins that I'm missing?

mpg321 only plays mpg/mp3 files; ossplay only plays raw files (like wav). Did you try the ogg with ogg123, xmms, mocp, or any other player?

I recommend mplayer.

That's a bug in the extension, thanks for reporting.

also, I tried: sudo vmixctl attach /dev/mixer1
error is: SNDCTL_ENGINEINFO: Invalid argument

This shouldn't be necessary, things should be automatic.

[s3704ssv]

@lucky13

I thought that they could cater other formats but thanks for the info!

@curaga

I'll try mplayer then.

also, is there a way for me to help out to fix this 'bug'? or how can I enable mixing with my audio device as currently only 1 app can access the audio device?

[s3704ssv]

to Moderators:

can we change the title to 'ALSA or OSS on AMD Geode LX800'

I don't know how to change it.

[curaga]

Fixed already. Try the updated extension, hopefully you'll have automatic vmix with that.

[s3704ssv]

@curaga

wow! very fast!, so..., I'll just download back OSS.tcz? and use it?

I'll try it after my work! and give feedback tomorrow then

Thanks!
