Summary: ICH5 S/PDIF audio drops out occasionally
Description:
I'm using the on-board audio of my Abit IC7-MAX3 ("Intel Corp. 82801EB/ER
(ICH5/ICH5R) AC'97 Audio Controller (rev 02)") with ALSA driver
snd_intel8x0 for my home theater setup. In every application I've tried,
which includes mythtv, xine, and ogg123, through both native alsa and OSS
emulation, the audio output from the S/PDIF port drops out for a second
every so often---maybe once a minute, or every few minutes; it's not
periodic.
I don't know whether analog output also drops out, since I don't have
analog output hooked up or enabled.
This is with the CVS build as of October 19. My asound.conf is:
pcm.krose-dmix {
type dmix
ipc_key 3516
ipc_key_add_uid yes
slave {
pcm "hw:0,4"
period_time 0
period_size 4096
#buffer_size 16384
buffer_size 131072
period_time 84000
buffer_time 340000
rate 48000
channels 2
}
bindings.0 0
bindings.1 1
}
pcm.dsp0 {
type plug
slave.pcm "krose-dmix"
}
ctl.mixer0 {
type hw
card 0
}
pcm.!default {
type plug
slave.pcm "krose-dmix"
}
I can't find any options to compile in debug logging: I'm not really sure
what the cause of the drop out is, e.g., buffer underrun, PCI contention,
etc. I'm happy to spend time to try to debug this, but I need a starting
point.
Of course, it'd also be great to know if anyone has ever seen this kind of
behavior before. I don't believe the SPD/IF port is turning itself off
because the receiver doesn't blip, which normally it would if the input
were to disappear temporarily.
The CPU is a 3.2G P4 with hyperthreading turned on. I never see the CPU
usage go above 50%.
Interestingly, I see similar behavior on my dual Opteron machine with an
AMD-8111 audio controller using the same driver (snd_intel8x0). I never
had this problem with the emu10k1 driver when I was using SB Lives, but I
have run into PCI slot limitations in my HTPC, so I have to use mobo
audio.
Suggestions?

Can you possibly give me a tip for where to put in some debugging printk's
to see if this is, for instance, a buffer underrun problem? Is the state
of the sound chip's buffer known anywhere in the driver where I can print
it out? When there's a buffer underrun, does the chip report this to the
driver? It seems like at the very least the driver should print a warning
when this happens, if it's possible to know that it *did* happen.

Incidentally, I compiled a low-latency kernel (Ingo Molnar's
realtime-preempt patches) to see if this would solve the problem, and it
doesn't appear to have. It's really unclear what's responsible for this
behavior at this point, because I'd figure a low-latency kernel would at
least make the problem much less likely were buffer underrun really the
issue. I'd really like to be able to determine for sure whether underrun
has occurred or not.

Summary: ICH5 S/PDIF audio drops out occasionally
Description:
I'm using the on-board audio of my Abit IC7-MAX3 ("Intel Corp. 82801EB/ER
(ICH5/ICH5R) AC'97 Audio Controller (rev 02)") with ALSA driver
snd_intel8x0 for my home theater setup. In every application I've tried,
which includes mythtv, xine, and ogg123, through both native alsa and OSS
emulation, the audio output from the S/PDIF port drops out for a second
every so often---maybe once a minute, or every few minutes; it's not
periodic.
I don't know whether analog output also drops out, since I don't have
analog output hooked up or enabled.
This is with the CVS build as of October 19. My asound.conf is:
pcm.krose-dmix {
type dmix
ipc_key 3516
ipc_key_add_uid yes
slave {
pcm "hw:0,4"
period_time 0
period_size 4096
#buffer_size 16384
buffer_size 131072
period_time 84000
buffer_time 340000
rate 48000
channels 2
}
bindings.0 0
bindings.1 1
}
pcm.dsp0 {
type plug
slave.pcm "krose-dmix"
}
ctl.mixer0 {
type hw
card 0
}
pcm.!default {
type plug
slave.pcm "krose-dmix"
}
I can't find any options to compile in debug logging: I'm not really sure
what the cause of the drop out is, e.g., buffer underrun, PCI contention,
etc. I'm happy to spend time to try to debug this, but I need a starting
point.
Of course, it'd also be great to know if anyone has ever seen this kind of
behavior before. I don't believe the SPD/IF port is turning itself off
because the receiver doesn't blip, which normally it would if the input
were to disappear temporarily.
The CPU is a 3.2G P4 with hyperthreading turned on. I never see the CPU
usage go above 50%.
Interestingly, I see similar behavior on my dual Opteron machine with an
AMD-8111 audio controller using the same driver (snd_intel8x0). I never
had this problem with the emu10k1 driver when I was using SB Lives, but I
have run into PCI slot limitations in my HTPC, so I have to use mobo
audio.
Suggestions?

Incidentally, I compiled a low-latency kernel (Ingo Molnar's
realtime-preempt patches) to see if this would solve the problem, and it
doesn't appear to have. It's really unclear what's responsible for this
behavior at this point, because I'd figure a low-latency kernel would at
least make the problem much less likely were buffer underrun really the
issue. I'd really like to be able to determine for sure whether underrun
has occurred or not.

----------------------------------------------------------------------
More info: this problem occurs with another digital receiver, so the
problem is either with (a) the software, (b) the mobo hardware, or (c) the
cable. I will try to eliminate (c) this week. :) FWIW, the drop-out is
much shorter on this receiver (Yamaha HTR-5650) than on the original one
(Marantz SR-7000). It's unclear to me whether this means the S/PDIF
signal is being interrupted, or if an underrun of the AC3 data is enough
to cause this effect.

You can turn on the xrun-detection by writing to a proc file,
# echo 2 > /proc/asound/card0/pcm4p/xrun_debug
where the directory corresponds to the PCM device to check.
Then you can know at least wheter detectable xrun happened.

So, when I do this, I don't actually see xruns in dmesg or
/var/log/messages for the behavior I'm referring to in this bug. (I see
them at other times, but that's a different issue.) So either my hardware
is screwed up and is occasionally dropping the toslink signal, or there's
some kind of reset going on in the driver or firmware that's not being
reported. Is there anything I can do short of replacing my motherboard?

A NOTE has been added to this issue.
======================================================================
<https://bugtrack.alsa-project.org/alsa-bug/view.php?id=589>

Reported By: squarooticus

Project: ALSA - driver
Issue ID: 589
Category: PCI - intel8x0
Reproducibility: always
Severity: minor
Priority: normal
Status: new
Distribution: Debian Unstable (sid)
Kernel Version: 2.6.7

Summary: ICH5 S/PDIF audio drops out occasionally
Description:
I'm using the on-board audio of my Abit IC7-MAX3 ("Intel Corp. 82801EB/ER
(ICH5/ICH5R) AC'97 Audio Controller (rev 02)") with ALSA driver
snd_intel8x0 for my home theater setup. In every application I've tried,
which includes mythtv, xine, and ogg123, through both native alsa and OSS
emulation, the audio output from the S/PDIF port drops out for a second
every so often---maybe once a minute, or every few minutes; it's not
periodic.
I don't know whether analog output also drops out, since I don't have
analog output hooked up or enabled.
This is with the CVS build as of October 19. My asound.conf is:
pcm.krose-dmix {
type dmix
ipc_key 3516
ipc_key_add_uid yes
slave {
pcm "hw:0,4"
period_time 0
period_size 4096
#buffer_size 16384
buffer_size 131072
period_time 84000
buffer_time 340000
rate 48000
channels 2
}
bindings.0 0
bindings.1 1
}
pcm.dsp0 {
type plug
slave.pcm "krose-dmix"
}
ctl.mixer0 {
type hw
card 0
}
pcm.!default {
type plug
slave.pcm "krose-dmix"
}
I can't find any options to compile in debug logging: I'm not really sure
what the cause of the drop out is, e.g., buffer underrun, PCI contention,
etc. I'm happy to spend time to try to debug this, but I need a starting
point.
Of course, it'd also be great to know if anyone has ever seen this kind of
behavior before. I don't believe the SPD/IF port is turning itself off
because the receiver doesn't blip, which normally it would if the input
were to disappear temporarily.
The CPU is a 3.2G P4 with hyperthreading turned on. I never see the CPU
usage go above 50%.
Interestingly, I see similar behavior on my dual Opteron machine with an
AMD-8111 audio controller using the same driver (snd_intel8x0). I never
had this problem with the emu10k1 driver when I was using SB Lives, but I
have run into PCI slot limitations in my HTPC, so I have to use mobo
audio.
Suggestions?

Here's another thread:

This makes it sound like there's a software workaround for this.
