Mandriva: how to disable pulseaudio and enable Alsa
I have another thread about getting my Tascam USB to work in Ubuntu, but I have since scrapped that distro in hopes of getting it to work in Mandriva 2009. I don't think I am fully configured for Alsa. I am using the default install with 2.6.29-rc6.
lsusb , cat /proc/asound/cards and modules both show my card available, lsmod shows everything as OK as far as I can see (will post it when i get home) , and of course dmesg shows a full detection (make/model/brand etc). Keep in mind , this is a USB sound. So i think it is safe to say my card is detecting.. this is good (i didn't get this far in Ubuntu )
When I go into Control center/hardware/sound it shows no devices also aplay - L just says "List of playback devices" with nothing else. amixer shows a master output only (i am able to raise/lower volume) but no other controls.
So with all the info given, how can I be sure Alsa is fully loaded and what can I check as far as configuration? alsa start shows "alsa drivers already loaded" as well. How can I disable this pulse and get alsa to work with my detected card?
You can disable PulseAudio in MCC. Open it, you need the root password. Click 'Hardware' and then 'Sound Configuration'.
There is check box to enable Pulse so just uncheck it. That disables Pulse. You may find later you need a aRts, if you expect to hear sound from more than one source at the same time.
Why are you running a release candidate? RC6? 2009.1 is stable. Any release candidate may be buggy....
As for Alsa, you need the correct module for your card modprobed. Then the correct adjustments will show up. I have never configured a USB sound card. Post the exact make, model etc. Possibly we can help determining what module to probe.

Thank you for your help.. I have a Tascam US-122L which uses the snd_usb_us122l module. Supposidly this device did not work in anything pre 2.6.29.rc3 because of a bug with ehci-hcd (usb 2.0). To be honest, I had a hard time figuring out the kernel upgrade with Mandriva and was suprised of how there is almost no guides on the net for it (Mandriva).
When I goto MCC . Hard / Sound it says I have no devices .. so there are no options to check / uncheck.
So looking at lsmod , I see usbcore is missing snd_usb_audio (or so i think it is supposed to be there). So is this included with any of the alsa packages, or is it a module that i need to modify my kernel for?
[root@localhost jay]# cat /proc/asound/cards
0 [US122L ]: USB US-122L - TASCAM US-122L

So i am thinking the missing piece is snd_usb_audio.. please help
downloaded alsa drivers, compiled and installed. snd_usb_audio now loaded.
aplay -l
[root@localhost jay]# aplay -l
**** List of PLAYBACK Hardware Devices ****

no devices listed .. ugh..
also...MCC / HARDWARE /SOUND CONFIGURATION
Code:
No Sound Card has been detected on your machine. Please verify that a Linux-supported Sound Card is correctly plugged in.
You can visit our hardware database at:

Note: if you've an ISA PnP sound card, you'll have to use the alsaconf or the sndconfig program. Just type "alsaconf" or "sndconfig" in a console.
