Bug 17542

Summary:	[sound] random static with GUS PnP
Product:	Base System	Reporter:	ken <ken>
Component:	kern	Assignee:	greid
Status:	Closed FIXED
Severity:	Affects Only Me
Priority:	Normal
Version:	4.0-CURRENT
Hardware:	Any
OS:	Any

Description ken 2000-03-22 04:20:00 UTC

The problem is that I sometimes get static instead of normal sound when I
play sound files with one of the following applications compiled from the
ports tree:

 - mpg123
 - amp
 - pcmplay (comes with tosha)
 - waveplay 

If I control-C out of the sound file once the static starts, and then start
it again, usually I don't get any static.

I think in general, this happens 1 in 10 or 20 times I try to play a sound
file.

For what it's worth, both Voxware (after Amancio hacked on it for a while)
and Luigi's pcm code didn't behave like this,

This has been a problem since the newpcm introduction.

Sometimes, after I've gotten static while playing a sound file, I hear a
hissing sound in either the left or right channel from subsequent sound
files.  There are only two ways I know of to "fix" that behavior:

 - reboot the box
 - keep cranking up sound player programs and ^C out of them until I get
   another round of static.  Usually this will take care of the problem.

Recompiling the applications and/or updating to newer versions doesn't
help.  Also, this can happen with any sound file I've tried.  Most of the
sound files I'm using are 16bit, 44KHz stereo.

Let me know if more information is needed.

Fix: 

If I knew, this wouldn't be a problem. :)
How-To-Repeat: 
See above.

Is this still a problem with more recent sources?

Re-opening this, putting this in feedback.  I actually sent feedback to 
greid and cg, but never got a response.  I just didn't CC it to 
freebsd-gnats-submit.

It was still a problem as of August, 2000.  I haven't upgraded the version
of -current on that machine since.  (It's an SMP box, and my main mail
gateway. :)

To try it out with a more recent -current I'd have to move it to a
different machine.  

If you really want more feedback, I may be able to move it this weekend.
Before I spend time doing that, it might be good to get some idea from
Cameron whether he thinks this might have been fixed.

The last significant change to the GUS driver was in July 2000.  It has
been broken since newpcm was introduced in 1999.

FYI, this is still a problem in -stable as of September 21st.

Is this still a problem with modern versions of FreeBSD?

I haven't tried it in years, probably since the last feedback I sent in
September 2001. :)

It's been so long since this PR came in (and since the submitter tried it) 
that this PR is just stale and should be closed.
