[ltp] Anyone tried 2.2.17 sound on a TP600X?

[Bjorn Knutsson]

I just downloaded and installed 2.2.17 on my TP600X (2645-5FG). Since the
cs4614 now supposedly is supported by the kernel, I switched from ALSA to the
native support. When I later boot, it seems that everything is detected
properly:

Sep  5 15:10:10 foobar kernel: Crystal 4280/461x + AC97 Audio, version 0.13, 14:55:10 Sep  5 2000 
Sep  5 15:10:10 foobar kernel: cs461x: Card found at 0x50100000 and 0x50000000, IRQ 11 
Sep  5 15:10:10 foobar kernel: cs461x: Thinkpad 600X/A20/T20 at 0x50100000/0x50000000, IRQ 11 
Sep  5 15:10:10 foobar kernel: ac97_codec: AC97 Audio codec, vendor id1: 0x4352, id2: 0x5913 (Cirrus Logic CS4297A) 
Sep  5 15:10:10 foobar kernel: cs461x: Found 1 audio device(s).

However, when I try to run aumix to adjust the output levels, I get a seemingly
infinite amount of AC'97 read/write problems:

Sep  5 15:42:05 foobar kernel: cs461x: AC'97 read problem (ACCTL_DCV), reg = 0x1a 
Sep  5 15:42:10 foobar last message repeated 28 times
Sep  5 15:42:10 foobar kernel: cs461x: AC'97 write problem, reg = 0x2, val = 0x3d3d 
Sep  5 15:42:10 foobar kernel: cs461x: AC'97 write problem, reg = 0x2, val = 0x3b3b

When I recompiled the kernel without the native support and install ALSA again,
everything works fine as before.

Anyone else tried it and got it to work?
