Description Michal Jaegermann 2001-06-12 01:04:25 UTC
Description of Problem:
With Alpha UP1100 and its built-in sound card I am getting
with 2.2.19aa2 the following:

Trident 4DWave/SiS 7018/Ali 5451 PCI Audio, version 0.14.6a, 19:28:59 Apr
30 2001
trident: ALi Audio Accelerator found at IO 0x10000, IRQ 10
ac97_codec: AC97  codec, vendor id1: 0x0000, id2: 0x0000 (Unknown)
ac97_codec: Secondary ac97 codec not present
trident: Running on Alpha system type Nautilus

and I can play various sounds and CDs.

With a kernel 2.4.3-7 from RC1 I see this:

Trident 4DWave/SiS 7018/ALi 5451 PCI Audio, version 0.14.6, 16:08:06 May 21
trident: ALi Audio Accelerator found at IO 0x8000, IRQ 10
ac97_codec: AC97  codec, id: 0x0000:0x0000 (Unknown)
ac97_codec: Secondary ac97 codec not present

and there is not a single peep.

How Reproducible:
Seems to be a property of all 2.4 kernels I tried so far.  Sigh!


Comment 1 Michal Jaegermann 2001-06-15 02:03:55 UTC
The problem is that a "generic" Alpha kernel on Nautilus does not have
a proper initialization code for a Nautilus sound card.  A copy of this
code from 2.2.19 kernel solves the problem. Header comments clearly
show that DRIVER_VERSION define was forgotten in updates.

This patch is done with 2.4.5-ac13 kernel but it will fit trident.c in
all 2.4.x, so far, kernels possibly with some offsets.  The patch will
be submitted on linux-kernel list and is attached. My patched kernel
plays now very loudly. :-)

Added for inclusion in a future erratta kernel
(not current one thats being QA'd though this was 2 days ltoo late for that,
