ALSA - Kernel - Aureal problem? Unresolved symbol wait_ms
 

I'm trying to build a Mythtv system on Fedora Core 2. However I've been having intermittent sound issues. Playback is sometimes too fast. It turns out this is a bug in the iteration of the openvortex aureal driver that went out with kernel 2.6.5. Since I've been struggling with other issues with this kernel, I upgraded to 2.6.7-1.499_7.rhfc2.at from ATrpms. Unfortunately, now I can't install the module for my sound card at all. When I try I get the following message:

snd_au8830: Unknown symbol wait_ms

I thought this might be an issue with the prebuilt alsa module for this kernel, so I downloaded the latest alsa, 1.0.6a, and built it from source (driver, lib and utils). Unfortunately I still get the above error message. No change.

My trouble is I can't find a solution to this problem anywhere. It is mentioned in several mailing lists related to networking hardware, and in one case even as an aureal card issue, but in every case the error is one of a number of errors, and they are trying to solve a different one. I can't find anyone else trying to fix this! :(

Anyhow, if anyone has any thoughts, I'd sure appreciate it! (At least, thoughts other than "buy a new soundcard." I have an old SB Live! laying around, but the aureal has more convenient connections -- and has been working fine in this machine for years -- at least before I upgraded to FC2.)

The machine: Duron 650@800 MHz, 512MB PC133, Asus A7V (Via KT133), GeForce2 GTS, Yuan MPG600 IVTV -- working fine on both the old and new kernel, Turtle Beach Montego 2 Quadzilla (Aureal 8830), Linksys 10/100 Ethernet card, a Maxtor 10GB, and a Maxtor 9GB both running on the onboard promise controller.

Excuse me but my English is worst:-0

I was in the same trouble.
My card is Vortex2.Kernel-2.6.8 Debian Sid.
So something may be deferent.

wait_ms defined in the game_port.
So I disabled game support of the kernel.
recompiled kernel and alsa-modules. Then rebooted,redo alsaconf.
And I got the sound.

Thanks for responding! Honestly, I had already given up and gone back to 2.6.5 and resolved the playback speed issues by upgrading the version of alsa I was running against this kernel.

I'll keep this in mind though, as I'm sure I'll decide to go for a newer kernel again in the not too distant future.
