Laptop Sound?

Laptop Sound?

[Deirdre Saoirse]

I have a Compaq Presario 1625 and, using SuSE 5.3, it has OpenSound
3.7.1z, which I installed. The chipset for the motherboard is an ESS
chipset (can't remember which one offhand), but OSS seemed to find it
fine.

However, it chops up mp3s *horribly*. I used to use amp (which I lost in a
hardware malfunction) on my desktop. I now use xaudio and mpg123, both of
which work fine on my desktop but give EXTREMELY choppy audio on the
laptop. Both the desktop and the laptop are K6/266.

Thinking I might try something less dramatic than mp3s, I tried playing
CDs from the console, which works fine. However, I don't know if that's
going through the sound driver or what (I have no kernel sound support).

Any ideas? Thanks.

Playing a CD usually happens using the sound card's analog mixer, not with
the sound output.

My guess is that your laptop is using power-saving features including
slowing down the CPU, and the MP3's aren't being decompressed fast enough.  
But that's only a guess.

That's what I thought.

I have that feature disabled in the BIOS however, so I know it's not that.

BTW, I wrote OpenSound and asked. Their response was that I probably had
my sound IRQ set to 7, which was, by default, the parallel port. This
would cause choppy sound.

Indeed, it was set to IRQ 7. I can't wait until everyone goes home so I
can test this hypothesis and see if this is, indeed, the issue. :)
