Re: [fluid-dev] Number of bits of audio data

I have experienced a problem with noisey sound with fluid with via 82xx
sound chips.  It turns out that the snd-via82xx driver is the problem.

To see if that's the same problem, download vias own "viaudiocombo" driver,
which is available on their website.  It's an oss driver and the latency is
too high to be of any use but the funny noises stop.

Upgrading to alsa 1.0.9b should help somewhat, though I still get funny
noises when fluid goes from silence to notes coming out. and when the last
note turns off.

I'm still trying to sort this out on my machine too, so would be grateful of
hearing more.

Hope this helps,

John Matthews.

Not sure if this is a silly question, but how many bits does Fluidsynth
use for audio data? Reason for asking is that I seem to be running into trouble with audible quantising distortion on quiet sounds. I was considering getting a 24-bit soundcard to see if that helps but it's probably pretty pointless if Fluid only generates 16-bit sound.

Sometimes it seems as though the audible artifacts are worse as the reverberation dies away.

I'm currently using Fluid 1.0.6 with Alsa 1.0.8 and kernel 2.4.29 on a mobo with Via 82C686B audio chip, if that's of any use to know. I'm looking at a Soundblaster Live 24-bit, which I believe Alsa supports, but am open to any suggestions!

Cheers,  Gerald.
