Mplayer Hissing Sounds
 

Whenever I play a .bin of an SVCD or VCD the sound hisses. It's not the image because I have burned them an played them through Mplayer and a DVD Player and they work fine. I have tried OSS and Alsa as the outputs and neither have seemed to work. I'm using SuSE 9.1 and usually run KDE.

do you have dma enabled on your hard drive?

hdparm -d1 /dev/hda

also, can I ask how you mounted the bin? I thought only iso's could be mounted.

Mplayer will play .bins and .dat files as well. Nice side effect of using it. :D

Should I enable DMA on both the drive in which the .bin is being played from, or the drive in which mPlayer is on. And mPlayer can play .bin's but a way to mount them is cdemu.

It wouldn't hurt to enable DMA on both drives. In fact, you'll probably see a small increase in general performance, (but it might not be whats causing the hissing sound...)

You should enable dma on any drive that's capable of handling it, as you're machine will react so much faster.

DMA is not this guys problem. This is a documented Fedora bug. I just read an article from osnews.com that gave the same problem. here is an excerpt

==========
Of all of FC2's warts, this has turned out to be the most annoying problem. I don't know how many people suffer from it, but it happens with every sound card I have. I hereby thank Peg Gallo for sending the fix to me: In KDE, start KMix (Main Menu --> Sound & Video --> KMix), click the Input tab, and check the "Advanced" box. You will see one or more devices called "IEC958." One of them is the culprit; turn them off until you find the right one.

" This is a documented Fedora bug"

Explains why I haven't come across it in all my distro-hopping. I've never tried on the hat...

I am currently running SuSE 9.1. I havn't updated my side thing. But I'll read about turning off that thing and return with my results.

Turning off IEC958 did not seem to do a thing. I may try booting into a Knoppix CD and seeing if it's a SuSE problem also. Any other suggestions would be nice.
