ATI SBx00 sound

shepper · 09-23-2009, 01:25 PM

In an arch install the sound in aplay, audacious and rhythmbox and flash plays way too fast and sound scratchy. I think it has something to do with the sampling rate but I'm lost after that.
At the present time udev loads the alsadrivers although I have tried various /etc/modprobe.d/sound configurations without success.

Any help appreciated

You need to know that in the kernel hda_Intel has it's own menu offering support for all kinds of chipsets.
Those ATI chips are awfully close to the API,

I have an sb600, I have support for Analog Devices, ATI, Intel, and generic enabled, and mine works.

Thanks for the reply. I have an SB600 working on another system in ARCH Linux that did not require any post-install configuration.

It looks like you are talking about a custom kernel with

Device/Drivers/Sound Card Support/Alsa/PCI Devices/Intel HD Audio

I am running the stock kernel at the present time and was wondering if I could set the options of the card using modprobe? Arch uses a rolling update system and the kernel is updated about 1-2x/month. We are due for kernel 2.6.31 sometime soon. At the time of this post a current ARCH is using 2.6.30 and I note that alot of kernel revisions in the intel-hda sound driver have occurred.

Anyone got the latest SBx00 working?

With each kernel comes a config-version in /boot. Why not grep that and see if the stock kernel is supporting your card. If not, complain!
