Slackware Sound Problems


Hey all, i tried searching the forum archives but was unable to come up with anything.

I've got a Creative Sound Blaster X-Fi Xtreme Audio PCI card that i'd like to get working with linux (I have no sound otherwise). Prior to buying the card, I went to the ALSA site to make sure it was supported.

I have a fresh install of Slackware 11 with the 2.4.33.3 kernel. Install went smooth and all seemed to be ok. When i started KDE I recieved no error messages. I used alsamixer to turn up the volumes and tried to listen to an MP3 and CD. No audio for either. The players ran fine, no errors messages there was just no audio. I tried running alsaconf and it finds ca0106 Creative Labs SB Audigy LS and loads the modules for it. Here is the output of lspci:

Code:

here is the output of lsmod:

I can only think that you have your volume muted. After openning alsamixer press M for each channel and unmute it (MM turns to a ## indicating volume level).

Just for reference, you need to properly configure your kernel to have proper sound.
Other reasons your might not be able to hear sound is when the sound card is locked by some other app - usually happens only with OSS apps, or ESD, or ARTS.

You could also try the 2.6 kernel; it kicks ass .

Thanks for your input. I was able to verify that the sound was not muted. I'm a little confused as to what you mean by "you need to properly configure your kernel to have proper sound". Is loading the modules not enough? Another question, do my lsmod and lspci outputs look normal? Sorry for the extra questions and thanks again for the help.

Your lspci and lsmod outputs are ok. By properly configuring your kernel I mean selecting all the sound modules you need, the proper ones for your sound card.
Code:
Device Drivers -> Sound
<*> Sound card support
        Advanced Linux Sound Architecture
                 <M> Advanced Linux Sound Architecture
                 <M> Sequncer Support
                 <M> Sequencer dummy client
                 <M> OSS PCM API
                 <M> RTC Timer Support
                 [*] Use RTC as default sequencer timer
                 [*] Verbose procfs
                        PCI devices
                                 <M> SB Audigy LS / Live 24bit
                                 <M> Emu10k1 (SB Live!, Audigy, E-mu APS)
Open Sound Sytem 
        < > Open Sound System (Deprecated)
So basically OSS disabled, OSS Alsa emulation API enabled and almost all other alsa modules built as modules, except for sound card support module, and of course only the PCI devices you need. I know SB Live! Audigy cards are based on the Emu10k1 processor so I select both drivers. You may need both. After you get your kernel ok, install or compile alsa-utils, alsa-tools, alsa-headers, alsa-firmware, alsa-plugins, alsa-oss, alsa-lib but don't install alsa-drivers, because you already use the kernel modules. Then run alsaconf and select your sound card. After it's done, use alsamixer to set your volume up and save it for next reboots...

You can unmute the sound card from the command line try this and see if this works

Code:
amixer set 'Master' 60% unmute
amixer set 'PCM' 100% unmute
