intel8x0: no sound in 2.6.11 rc3 & 4 (fine with 2.6.10)

[uaca]

Hello

I have read a post in lkml.org that states that the problem experienced in
rc3 has gone (1). That is not the case for me.

My audio device is

0000:00:1f.5 Multimedia audio controller: Intel Corp. 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (rev 01)
        Subsystem: IBM: Unknown device 0554
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B-
        Status: Cap+ 66MHz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 0
        Interrupt: pin B routed to IRQ 11
        Region 0: I/O ports at 1c00 [size=256]
        Region 1: I/O ports at 18c0 [size=64]
        Region 2: Memory at d0100c00 (32-bit, non-prefetchable) [size=512]
        Region 3: Memory at d0100800 (32-bit, non-prefetchable) [size=256]
        Capabilities: [50] Power Management version 2
                Flags: PMEClk- DSI- D1- D2- AuxCurrent=375mA PME(D0+,D1-,D2-,D3hot+,D3cold+)
                Status: D0 PME-Enable- DSel=0 DScale=0 PME-

In 2.6.10 and in 2.6.11-rc3 & 4 the clock is set to 48khz.

eg:

intel8x0_measure_ac97_clock: measured 49502 usecs
intel8x0: clocking to 48000

It uses an Analog Devices AD1981B

I have put a tar file of the /proc/asound directory of 2.6.10 and 2.6.11-rc4 in

	http://pusa.uv.es/~ulisses/asound-intel8x0/

the tar files were done while playing pcm audio, (not being eard in rc4).

I have found that I had to Mute __both__ "Headphone Jack Sense" and
"Line Jack Sense" in order to ear the audio in rc4.

Please let me know if you need further info or you want a tester

All this is on a IBM Thinkpad R51 - Type 2887 -AVG

(tot toc: IBM, we're buying your laptops too)

Thanks in advance

	Ulisses
