Thank you for replying. I play the same mp3 on my FC6 and WinXP on the same PC using the same speakers. But they sounds really different. I find the music turns crappy in FC6. I use default settings for the equalizers/mixers etc. For acapella music, it does not sound too differently between that in FC6 and WinXP. The 'crappiness' of the music is more significant when the drums, bass, etc come in the music. The music sounds like it is played on old bad speakers. Sorry for my bad English. I hope you can understand what I am trying to express. ^.^" I just found out that when I play the mp3 in mpg321 in terminal, it sounds as good as it is played in Windows. But when the same song is played using other players, they sound much worse than that. I do not know what this could mean but I hope by stating this can help someone to identify the problem and eventually help me to overcome it. =) <div>On 5/13/07, Tim <<a href="mailto:ignored_mailbox@yahoo.com.au">ignored_mailbox@yahoo.com.au</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> On Sun, 2007-05-13 at 17:05 +0800, Guo Lin wrote: > Hi, I am a very new user of Fedora Core 6.

Beyond some fault causing distortion, I can't see why one would be different than the other, it's the same hardware producing the sound. The only think I can think of is: Are you boosting the bass in Windows, and noticing that difference? I haven't seen tone controls on a Linux control panel, and artificially boosting bass doesn't really compensate for crappy speakers. The other thing that springs to mind, is having a duff audio cable, where the ground isn't properly connected. Instead of getting left and right signals, you end up with a mono signal comprised of left minus right, which seriously drops the bass down, as well as introducing other odd phasing errors. What are you playing, though? And how are you listening? MP3s were notorious for having crap bass, and a less than brilliant decoder doesn't help. And what do you mean by bad? Distorting? Lacking in bass? Something else? For what it's worth, on my various PCs, the sound sounds the same whatever OS is driving it. For any file format (an ogg on Windows versus an ogg on Linux, and so on, but not ogg versus MP3), and whether using those crappy PC speakers, or the Wharfedales on the stereo system. -- (This box runs FC6, my others run FC4 & FC5, in case that's important to the thread.)
