* Environment
Kernel: 3.1.4-1
DM: XFCE 4.8
Sound card: ICE1724
Using alsa as default sound output
* Issue: after system upgrade, unable to play any sound
speaker-test -c 2: no sound
mplayer: no sound, and mplayer just hang there, didn't start play (tried ao=alsa)
smplayer: report mplayer crash

vlc: I can scroll playback bar, but still no sound, and no output in static information
* Tried solution
reinstall alsa-util, alsa-libs, mplayer
use alsaconf to set soundcard
unmute alsamixer
instal pulseaudio-alsa, also specified ao=pulse in mplayer or vlc
downgrade linux to 3.1.1-1, 3.1-4
but none of them fix the problem
* Supecteded package: kernel
** Live USB works normal
I have a live USB installed Arch linux with kernel 3.0.7 and Gnome 3,
use pulseaudio as default sound output, everything works fine, and the
system info almost identical with what I list below
** Busybox (?) works normal
When checking if this is a hardware issue, I accidently reset BIOS time,
when I boot into Arch, recieve some error message like "last mount time in
the future, enter admin password to fix or Ctrl-D to continue" ( is this
envionment in busybox ? ) After I enter the admin pwd, login as root,
remount hd, then I test mplayer and speaker-test, both work normal,
but after reboot, the issue cames back
* some system information FYI
aplay -l

ICEnsemble ICE1724 at 0xd000, irq 17Because of virtualbox-modules dep, haven't tried to downgrade to linux 3.0.7 yet
Does anyone encounter some issue like this, is it related to kernel or something else ?
that upgrade also upgrade lots of packages like lame, libmatroska, ffmpeg ......
also tried to downgrade these packages, but still unable to fix the sound issue

Upgrade kernel to 3.1.5 still not fix the sound issue
On 12/14, I upgraded imagemagick, pcre, texinfo, virtualbox-modules, wxgtk with `pacman -Syu`,
after reboot, the sound comes back, everything works fine just like before
But on 12/16, I lost the sound again, only found these line in kernel.org
Dec 16 09:28:29 localhost kernel: [75508.452468] ice1724: Too long irq loop, status = 0xff
Dec 16 09:28:29 localhost kernel: [75508.452468] ice1724: Disabling MPU_TXno matter how I tried to reproduce the upgrade on 12/14, still unable to fix the
issue, and those warning didn't show up again, I also boot into live USB to check
if this is hardware problem, but sound works normal in live USB
it's so weird... ![]()
