Software:
Mandrake Linux Version 9.0 SMP Kernel with all updates running KDE
Problem:
The installed Mandrake 9.0 with the alsa driver, snd-cs46xx, for the Turtle Beach Santa Cruz
sound card will freeze when opening the KDE windows manager. Requires a power off to
gain control of the computer.
Situation:
The problem first occured when updating to the new ML 9.0 from a working 8.2 system. The update went without a problem, all packages installed correctly, up and until the first reboot.
At the stage when starting the KDE windows manager the computer froze. The only way to get out was to turn off the computer at the power button or reset switch. This was attempted numerous times with the same results.
We then replaced the Turtle Beach Santa Cruz sound card with a Sound Blaster
Live! 5.1. After replacing the sound card the computer booted and ran without
problems.
We tried everything imagiable to get the card working with the alsa snd-cs46xx driver, tweaking the BIOS and various boot switches. Nothing worked with the Santa Cruz sound and the alsa drivers.
One thing notices was in the /var/log/kernel/errors file:
1. "Oct 5 18:03:05 sword kernel: cs46xx: cs46xx_setup_eapd_slot() Failure to
write the GPIO pins for slot 12".
This was the only error that addresses the sound card.
Present:
Now running Mandrake Linux 9.0 with the OSS drivers, cs46xx Santa Cruz card.
The system runs well with this driver.
Question:
Has any one with the same or similar hardware experienced this problem and
what was the outcome?
Why does the alsa sound drivers for the cs46xx not work with the smp kernel?
Thank you
Larry
