Default CD audio player read speed?

Does anyone know if there's a way to limit the read speed of an audio CD player on OpenBSD?

The player built into my laptop roars and vibrates like a jet engine whenever I play a music CD -- seems like it's running at full tilt 100% of the time. From what I've read, it just needs to be running at 1x to read audio data.

I've tried cdio(1) and four different GUI players. As far as I can tell, none of them have an option to enable read-speed regulation.

cdparanoia(1) has a --force-read-speed number option, but requires saving to a file or redirecting to stdout.

This program is exactly what I'm looking for. Unfortunately, it's for Win... I couldn't find anything like it at http://openports.se when I tried searching for 'cd' and 'dvd'.

dmesg:
Code:
cd0 at scsibus1 targ 1 lun 0: <HL-DT-ST, DVDRAM GU10N, MX05> ATAPI 5/cdrom removable
The player appears to be a Hitachi-LG DVD drive. Does that make a difference?

Try $ cdparanoia -S 1 -Z 1 - | aucat -i -, which should force the speed to 1X, do no error correction, and pipe the first track to aucat(1).

$ cdparanoia -S 1 -Z 1 - | aucat -i - didn't work. I tried different speeds (-S 2, -S 4, -S 6). That didn't make a difference.

Maybe this player just isn't up to the task. It's a laptop player after all -- not exactly high-end.

Ripping the tracks to a file for playback is another possibility, but that's a project for later.

In the meantime, thanks for the ideas.

In the future, then, you may find audio/abcde helpful.
