i've got new laptop since i reported this bug.
I've stumbled upon a bug when using Cinelerra (video editing software),
and since then i have patched the software to ignore the excessively wrong
results gotten from SNDCTL_DSP_GETOPTR
if(!ioctl(get_output(0), SNDCTL_DSP_GETOPTR, &info))
{
//printf("AudioOSS::device_position %d %d %d\n", info.bytes,
device->get_obits(), device->get_ochannels());
// workaround for ALSA OSS emulation driver's bug
// the problem is that if the first write to sound device was not full
lenght fragment then
// _GETOPTR returns insanely large numbers at first moments of play
if (info.bytes > 2100000000)
return 0;
else
return info.bytes /
(device->get_obits() / 8) /
device->get_ochannels();
}

We are seeing the same problem for ibmtts on Fedora Core 3 using Gnome
2.10.1 & gnome-speech 0.3.6. I would like to request increasing the
priority on this 8 month old bug because it is impacting accessibility on
Linux.

Did you try the latest ALSA driver?

It's not the alsa-utils but ALSA drivers in kernel.
I won't be surprised if it was already fixed in ALSA 1.0.9rc3 :)

I'm running FC3 with the 2.6.10-1.766_FC3 kernel. How can I determine
which level of ALSA the kernel is using?

I'm running FC3 with the 2.6.10-1.766_FC3 kernel. How can I determine
which level of ALSA the kernel is using?

I'm trying to test this on FC4 test 3 with alsa driver 1.0.9rc3. grep isn't
turning up the original lines reported as causing the problem so maybe
they've been removed. Can someone point me to the file where this
problematic code was originally located?
There's still a clipping problem using alsa with gnome speech. I'd like to
see if it's being caused by this same bug.

not the code from alsa, but something an application writer can do to get
around of the bug in ALSA. I have not investigated where in ALSA the bug
actually lies.

Summary: Fixes bug 557: SNDCTL_DSP_GETOPTR not working correctly
This patch changes snd_pcm_oss_bytes() by adding a local variable
for the frames -> bytes conversion, which means that the frame count
is no longer corrupted by this conversion.

It seems like a wrong patch to me. We cannot mix frames with bytes (see
last expression). I think that there might be an overflow in the return
expression.

Summary: SNDCTL_DSP_GETOPTR not working correctly in specific
situation
Description:
When the first few writes to the oss emulation device are done in specific
way, SNDCTL_DSP_GETOPTR returns wrongly huge results in info.bytes
======================================================================

perex - 05-27-05 11:04

parente - 05-27-05 15:41
----------------------------------------------------------------------
perex: The fix2.patch does not work on my system. It compiles, but refuses
to be inserted into the kernel with a "symbol error." (Probably because
int64 isn't recognized on my system?)
I also tried just casting to regular "int" but that does not solve the
problem. Output from gnome-speech is still clipped.
What about the patch submitted by Roger Mach? I can compile and install
it, and it appears to correct the problem without introducing others.
Maybe the last expression computes the number of bytes properly using the
number of frames?

perex: I can now compile and insert the module into the kernel on my
machine.
However, the clipping problem still remains. Considering that Roger Mach's
patch works, I do not believe this is an overflow problem. Rather, the bug
seems to stem from an incorrect calculation involving bytes instead of the
desired frames.

i've got new laptop since i reported this bug.
I've stumbled upon a bug when using Cinelerra (video editing software),
and since then i have patched the software to ignore the excessively wrong
results gotten from SNDCTL_DSP_GETOPTR
if(!ioctl(get_output(0), SNDCTL_DSP_GETOPTR, &info))
{
//printf("AudioOSS::device_position %d %d %d\n", info.bytes,
device->get_obits(), device->get_ochannels());
// workaround for ALSA OSS emulation driver's bug
// the problem is that if the first write to sound device was not full
lenght fragment then
// _GETOPTR returns insanely large numbers at first moments of play
if (info.bytes > 2100000000)
return 0;
else
return info.bytes /
(device->get_obits() / 8) /
device->get_ochannels();
}

We are seeing the same problem for ibmtts on Fedora Core 3 using Gnome
2.10.1 & gnome-speech 0.3.6. I would like to request increasing the
priority on this 8 month old bug because it is impacting accessibility on
Linux.
----------------------------------------------------------------------
perex - 05-13-05 15:24
----------------------------------------------------------------------
Can someone write a short program / test utility which triggers this bug?
----------------------------------------------------------------------
tiwai - 05-13-05 15:26
----------------------------------------------------------------------
Did you try the latest ALSA driver?
It's not clear which version causes this problem.
----------------------------------------------------------------------
gk4 - 05-13-05 19:35
----------------------------------------------------------------------
FC3 is using alsa-utils-1.0.6-3. Have you expclicitly fixed this problem
in a particular release?
----------------------------------------------------------------------
tiwai - 05-13-05 19:38
----------------------------------------------------------------------
It's not the alsa-utils but ALSA drivers in kernel.
I won't be surprised if it was already fixed in ALSA 1.0.9rc3 :)
----------------------------------------------------------------------
gk4 - 05-13-05 19:48
----------------------------------------------------------------------
I'm running FC3 with the 2.6.10-1.766_FC3 kernel. How can I determine
which level of ALSA the kernel is using?
----------------------------------------------------------------------
tiwai - 05-15-05 15:50
----------------------------------------------------------------------
Check /proc/asound/version.
----------------------------------------------------------------------
gk4 - 05-16-05 16:08
----------------------------------------------------------------------
My /proc/asound/version file has:
Advanced Linux Sound Architecture Driver Version 1.0.6 (Sun Aug 15
07:17:53 2004 UTC). Compiled on Feb 9 2005 for kernel 2.6.10-1.766_FC3.
----------------------------------------------------------------------
parente - 05-19-05 15:28
----------------------------------------------------------------------
I'm trying to test this on FC4 test 3 with alsa driver 1.0.9rc3. grep isn't
turning up the original lines reported as causing the problem so maybe
they've been removed. Can someone point me to the file where this
problematic code was originally located?
There's still a clipping problem using alsa with gnome speech. I'd like to
see if it's being caused by this same bug.
----------------------------------------------------------------------
minmax - 05-20-05 00:38
----------------------------------------------------------------------
parente: The code that i posted is an example of WORKAROUND for the bug.
not the code from alsa, but something an application writer can do to get
around of the bug in ALSA. I have not investigated where in ALSA the bug
actually lies.

Summary: Fixes bug 557: SNDCTL_DSP_GETOPTR not working correctly
This patch changes snd_pcm_oss_bytes() by adding a local variable
for the frames -> bytes conversion, which means that the frame count
is no longer corrupted by this conversion.

It seems like a wrong patch to me. We cannot mix frames with bytes (see
last expression). I think that there might be an overflow in the return
expression.

Hmm, I'm just reading the code again, and afraid that the fix3 patch isn't
right, if I understand correctly.
oss.bytes for playback contains the bytes actually transferred to h/w
buffer, i.e. the OSS-adjusted position of appl_ptr. Then, getoptr.bytes
should return simply
oss.bytes - frames_to_bytes(delay)
without fixup. This means, setting fixup = 0 for playback should
suffice.
The above assumes that getoptr returns the "hwptr" for OSS.

Applied oss-optr-fix3.patch. Ran gnome-speech's test-speech utility
callback test. Speech is still clipped as before.

Nice situation :-) Two patches in one moment....
Takashi, I think that your patch pcm-oss-ptr-fix4.diff is not correct,
because info.blocks should count all buffered data from application (I may
be wrong of course).

I'm really puzzled what's the correct implementation of blocks.
And, yes, my patch isn't correct anyway for blocks field, but the current
implementation seems also wrong, too.
Looking at the other OSS/free codes, the blocks field contains basically
(snd_pcm_avail() / fragsize). That is, for playback, the empty space on
the ring buffer / fragsize.
So, it should be like
info.blocks = (runtime->oss.buffer_bytes - frames_to_bytes(delay) -
fixup) / runtime->oss.period_bytes;
for playback.

pcm-oss-ptr-fix4.diff appears to fix the problem. Speech is no longer
clipped in gnopernicus or test-speech.

Summary: SNDCTL_DSP_GETOPTR not working correctly in specific
situation
Description:
When the first few writes to the oss emulation device are done in specific
way, SNDCTL_DSP_GETOPTR returns wrongly huge results in info.bytes

pcm-oss-ptr-fix4.diff appears to fix the problem. Speech is no longer
clipped in gnopernicus or test-speech.

Ok, fix5 patch is available for review. I think that info.blocks is not
used in OSS apps, but we should follow the "standard" behaviour...
