Miscellaneous problems (sound, DVD writer, USB mp3 player)

[Joaquin Cuenca Abela]

Hi,

A month ago I commentted on some problems I had with Ubuntu
(basically, usb sound headset not working, USB mp3 player problems,
and printer printing random bits).

I reinstalled Ubuntu a few days ago (due to a problem unrelated to
Ubuntu). To my surprise, things are not going exactly like the last
time, namely:

* Built-in sound card is not working anymore (that's without plugging
my usb headset). (bad)
I think that I've tested any possible combination of alsamixer, but no
luck. Any ideas? Can I post something to help to diagnose this
problem?

* My CD-DVD writer is only able to burn CDs, but it doesn't burns
anymore DVD-RW's!
I tried nautilus & k3b, and both of them refuse to burn to Verbatim
DVD-RW, even though I was able to burn to these DVDs previously.

* I still have the same problem I had with my USB mp3 player. It
correctly sees a FAT-32 (I think) filesystem with ~256M, but when I
try to copy some files to the mp3 player, it says that there is not
enough space available (but "df" shows plenty of space!).

In /var/log/messages I get (when I plug the mp3 player and I try to
copy something to it):

usb 1-1: new full speed USB device using address 3

Any ideas?

Thank you for any help!

Cheers,

P.S.: I also had a problem with my Epson Stylus Color 680, but the
problem has vanished now, so there are not only regressions :-)
