RE: TP 390E sound garbled on resume
Hello,
Well, I have a couple Thinkpad 560 model machines, and use the suspend
and resume feature also. I mostly use RH on them. But, I can suggest that
you ensure that the sound daemon (esd in my case) is also restarted when
you resume the laptop.
Unfortunately, although I have been able to automate the unload/reload of
*all* the sound-related modules, I have never been able to automate the
shutdown/restart of the esd daemon. I tried for many hours, many times,
but was never successful. So, I just gave up, and manually restart the
sound daemon myself.
I would be interested if this advice is helpful, and if anyone has ever
solved
the esd shutdown/restart issue.

Subject: TP 390E sound garbled on resume

I've been quite happy with my Thinkpad 390E that I've had for just one
year. About a month ago I bought a new battery and have been using the
suspend capability when transporting it.
I discovered that upon resume any audio playback is extremely garbled.
I find this with either xmms or mplayer. When playing a video with
mplayer the audio is garbled and the video plays much slower than
normal. Audio plays normally only after a cold reboot.
I am using the ampd package and as near as I can tell the ALSA modules
are being unloaded before suspend and reloaded on resume. If the
modules are not unloaded then no audio can be heard at all after a
resume. I never experience machine hangs so I think this is probably a
hardware issue. The BIOS image is the second last version available
for the 390E series.
I am using a custom built 2.3.23 kernel and here is the APM portion of
my kernel config:
CONFIG_PM=y
CONFIG_APM=m
# CONFIG_APM_IGNORE_USER_SUSPEND is not set
# CONFIG_APM_DO_ENABLE is not set
CONFIG_APM_CPU_IDLE=y
CONFIG_APM_DISPLAY_BLANK=y
CONFIG_APM_RTC_IS_GMT=y
CONFIG_APM_ALLOW_INTS=y
# CONFIG_APM_REAL_MODE_POWER_OFF is not set
#
# ACPI Support
#
# CONFIG_ACPI is not set
# CONFIG_OPTIMISE_SIZE is not set
I don't believe this machine supports ACPI, therefore I've not enabled
it.
I'll entertain any and all ideas and pointers.
