Sorry, posted this to alsa-user, but recieved no reply, so I'm going to
try on here.
I have compiled kernel 2.5.5 and enabled ALSA support for my SBLive! PCI
card.
All the modules compiled except rtctimer, which I then disabled and
recompiled without a problem.
I modprobed the snd-emu10k1 driver - at this point a noticable hiss
started in my speakers. but I wasn't sure if it was just because I had
them up loud, so I continued.
I ran alsamixer, put up all the volumes (just to be sure) and then used
alsaplayer to play an Ogg Vorbis file. This was when I realised the
hiss was not just background noise - under the music the hiss was very
noticable. Using OSS from 2.4.x on the same hardware there is no such
hiss (or at least not noticable)
Has anyone seen this problem before and/or knows how to fix it?
Some potentially useful outputs, hope they help:
