Hello,
I have the following on-board audio controller that works fine with Kernel
2.6.12:
# lspci -vvv
0000:00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER
(ICH5/ICH5R) AC'97 Audio Controller (rev 02)
Subsystem: ASUSTeK Computer Inc. P4P800 Mainboard
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 22
Region 0: I/O ports at e800 [size=256]
Region 1: I/O ports at ee80 [size=64]
Region 2: Memory at febff800 (32-bit, non-prefetchable) [size=512]
Region 3: Memory at febff400 (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-
However, with kernel 2.6.15 it doesn't work. I get the following message
during booting:
# dmesg
...
ACPI: PCI Interrupt 0000:00:1f.5[B] -> GSI 17 (level, low) -> IRQ 22
PCI: Setting latency timer of device 0000:00:1f.5 to 64
AC'97 0 analog subsections not ready
intel8x0_measure_ac97_clock: measured 56104 usecs
intel8x0: clocking to 48000
...
My kernel-config is the following:
#
# Advanced Linux Sound Architecture
#
CONFIG_SND=m
CONFIG_SND_AC97_CODEC=m
CONFIG_SND_AC97_BUS=m
CONFIG_SND_TIMER=m
CONFIG_SND_PCM=m
CONFIG_SND_RAWMIDI=m
CONFIG_SND_SEQUENCER=m
# CONFIG_SND_SEQ_DUMMY is not set
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=m
CONFIG_SND_PCM_OSS=m
# CONFIG_SND_SEQUENCER_OSS is not set
CONFIG_SND_RTCTIMER=m
CONFIG_SND_SEQ_RTCTIMER_DEFAULT=y
# CONFIG_SND_VERBOSE_PRINTK is not set
# CONFIG_SND_DEBUG is not set
CONFIG_SND_GENERIC_DRIVER=y
The modules are loaded correctly:
snd_intel8x0 30748 0
snd_ac97_codec 83232 1 snd_intel8x0
snd_ac97_bus 2432 1 snd_ac97_codec
snd_pcm_oss 47264 0
snd_mixer_oss 17408 1 snd_pcm_oss
snd_pcm 81540 3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss
snd_timer 23684 1 snd_pcm
snd 52580 6
snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore 10336 1 snd
snd_page_alloc 10376 2 snd_intel8x0,snd_pcm
I also tried kernel 2.6.13 and it doesn't work either.
I am using Debian SID and compiled the kernel myself. For kernel 2.6.15 I used
the .config from kernel 2.6.12 and did make-oldconfig.
Is there anything I can do to make also work again with kernel 2.6.15?
Greetings,
Michael
