I use the build-in sound card which is advertised as
the NVIDIA MCP72XE/MCP72P/MCP78U/MCP78S High Definition Audio.
I know I should buy a more sophisticated card but boards like the
Terratec DMX6fire24/96 or M-Audio Delta 410 have prices here in Holland
which are way over the prices you pay (€189,00 is the cheapest).
Moreover I use it to edit using headphones as audio output for computers
is, in my opinion very bad or you use a pair of studio monitors (I use
Yamaha 60 W as output boxes for my E-piano for use in small rooms. As
I'm a jazz-pianist and people prefer to listen so you don't need
decibels to go over crowd noise!). But those are expensive.
My jack settings are:
/usr/bin/jackd -dalsa -dhw:0 -r44100 -p1024 -n2.
The humble hda can perform ridiculously well for what it is. I'd
recommend
replacing the '-n2' with '-S -n3'. The '-p1024' should be able to go
down to
'-p256' (or even lower) as well.
Also, I think the HDA's native rate is 48000, not 44100. At least the
ones in my two laptops are.
I've wondered about this native rate. I always set my onboard cards to
48Khz too but I've read here and there that it shouldn't matter,
especially with modern onboard cards.
Don't know - I don't have any of those around here. ;-)
I seem to remember seeing a system message or some other entry in a log
once (maybe something connected with ALSA?) that something had timed it
to 478##+ something and so was setting it to 48K.
And afaik -n3 is only useful with
USB1 cards that prefer a latency that is a multiple of their interrupt
period
(http://lists.linuxaudio.org/pipermail/linux-audio-user/2009-October/064013.html).
I use -n3 with my USB sound card. I generally don't use the onboard
audio for sound.
