Audio playback problems

Hi,
I recently installed QNX RTP on a machine I have at my apartment. It’s an
810 based motherboard, using the 810 audio and video drivers. I have the
same board in a machine I use at work.

I’ve installed QNX RTP on both machines. The amount of RAM in both is the
same, the network card is the same, processor is the same type and speed (I
think, maybe someone updated my machine at work without me knowing). Using
plaympegaudio_noph or the media player on my machine at work works fine.
MP3’s play great. Using the same program on my machine at home is different
somehow. Every audio file I play plays a sample and repeats the sample
once, plays the next piece, repeats it once, etc.

I have no idea why it would act this way. Looking at the system monitor,
the CPU load is constant (and at about 10%), memory usage is normal, network
load is 0 (playing the audio back on the hard drive).

Any hints, tips, tricks?

TIA,
Ron

Hello Ron,

If the systems are running the same hardware and OS then what could be
the problem is that there is a process of higher priority that is
starving the application. You can try increasing the priority of
plaympegaudio_noph and see if that helps. To do this have a look at
`slay´ in the help. Something else you can try is play a simple wav
file and see if you have the same problems.

Regards,
Dave B.

Hi Dave,
I just checked the priority of it (used slay to up the priority) and
there was no difference. I used psin to look at the priority of the process
and noticed the threads running at 10. I then started the playsound_noph
with nice to up the priority. Even at priority 25 it’s still getting
skipping sounds. I’m tempted to make a backup of some of my changes and
reinstall QNX RTP on the computer that’s acting up to see if it will be
reproduced.

Hello Ron,

I was just talking to someone here that had the same problem you are
having with your sound card. The problem was that the PnP OS wasn’t
disabled in the BIOS. Check your BIOS to see if this isn’t disabled and
if not, disable it and see if that helps.

Dave,
Nope, it’s disabled. I checked them beforehand just to be sure.

This is quite interesting at least. I mis-diagnosed the effect I was
hearing a tiny bit. It will play the first piece (about a second), then
play the ending half of that first piece plus the first half of the next
piece (which should have been played immediately after the first). At first
I thought it was replaying what it had already played, but I noticed that it
moves along a bit.

Kind of sounds like the following (each piece is a second of music)

[----------]
[----------]
[----------]

where it should sound like
[----------]
[----------]
[----------]

I’m going to see what might be different between the two machines. I know
the hard drive at least is different (the one I have here is 20GB, the in my
machine at work is 40GB), but that shouldn’t hurt audio playback…
