Problems with trident sound driver on Acer Travelmate Laptop
Last modified: 2007-04-18 12:51:33 EDT
Description of problem:
I have an Acer TravelMate 524TXV laptop with a trident based (ALI 5451) Sound
Card. On 'modprobe trident' or via the GNOME Based Sound card config tool the
sound card doesn't work.
Version-Release number of selected component (if applicable):
Redhat Linux Phoebe Beta - 15th Feb 2003
modprobe trident on laptop, look at dmesg output.
The X Windows interface complains unable to open sound device
Trident 4DWave/SiS 7018/ALi 5451,Tvia CyberPro 5050 PCI Audio, version 0.14.10h,
11:58:39 Feb 13 2003
PCI: Guessed IRQ 10 for device 00:06.0
trident: ALi Audio Accelerator found at IO 0x9000, IRQ 10
ALi 5451 did not come out of reset.
For sound to work.
Beta released with ISOs Dated 15th Feb 2003
PIII Laptop with 256Mb RAM, clean RedHat install dual booting with Windows 2000
It looks like this bug has been fixed in the driver update as per kernel 2.5.64
Quoted from the kernel changelog. Which appears to be the problem I have been
I think this is happening in earlier versions of Redhat as well (specifically
8.0 and possibly 7.3)
[PATCH] trident 1/3 fix "did not come out of reset"
The M5451 can sometimes not come out of reset. This is non fatal and it
continues to work fine, so print a nasty message but don't fail the driver
[PATCH] trident 2/3 make me the maintainer
Make Muli Ben-Yehuda the maintainer for trident as per Alan's suggestion
[PATCH] trident 3/3 use pr_debug instead of TRDBG
use the standard pr_debug macro instead of TRDBG
I have the same problem on Acer Travelmate 525txv, but did not have it in RH8.0.
The computer totally freezes during modprobe.
It works with ALSA-drivers from
85930 is the same thing.
Fixed in errata kernel
