----  [ 881183 ] ice1712 rattle noise with 1.0.1 ( kernel 2.6.1) ----

Device:
STaudio DSP2000

Problem:
All outputs make a rattling noise, peaking to the max levels, with alsa 
drivers 1.0.1 form kernel 2.6.1

Steps to reproduce:

1) Configure and install alsa drivers form Kernel 2.6.1 for PCI card ice1712
2) Play something with aplay, xmms or try run jackd
3) observe rattling noise.
( Ratling noise pitch increases with sampling frequency.

Workaround:

Use the same alsa options you selected in the kernel, with kernel 2.6.0  
( alsa 0.9.7 )

Summary:

ICE1712 works correctly with older alsa drivers ( 0.9.7). New drivers generate 
a rattling oise in all outputs.


Kernel options used in both cases:

#
# Advanced Linux Sound Architecture
#
CONFIG_SND=y
CONFIG_SND_SEQUENCER=y
# CONFIG_SND_SEQ_DUMMY is not set
CONFIG_SND_OSSEMUL=y
CONFIG_SND_MIXER_OSS=y
CONFIG_SND_PCM_OSS=y
CONFIG_SND_SEQUENCER_OSS=y
CONFIG_SND_RTCTIMER=y
# CONFIG_SND_VERBOSE_PRINTK is not set
# CONFIG_SND_DEBUG is not set

#
# Generic devices
#
# CONFIG_SND_DUMMY is not set
# CONFIG_SND_VIRMIDI is not set
# CONFIG_SND_MTPAV is not set
# CONFIG_SND_SERIAL_U16550 is not set
# CONFIG_SND_MPU401 is not set

Alsa libs tried:

alsa-lib-1.0.0_rc2-r1
alsa-lib-0.9.8
alsa-lib-1.0.1

( independently of which libraries you use, you get the same results )


Severity:

High
I gotta choose between having sound or kernel security updates.
