[PlanetCCRMA] FC2 feedback

[Lionel Chilaud]

Hello.

I have tested the "experimental" FC2 packages. 
Overall I found installation is very smooth (to the
light of previous experience)

I have: P4 2.8GHz-MSI865Neo with onboard audio.
I also have an external Sound Blaster Live platinum.

Soundcards:
hw:0 - SBLive 5.1 Platinum (snd-emu10k1)
hw:1 - On Board CMI codec 97' (snd-intel8x0) 

I recompiled the 2.6.7-1.437.1.ll.rhfc2.ccrma kernel
because I need ntfs...
Q: Is there any other parts I need to rebuild (like
alsa kernel modules ???) Or is it included in the
/usr/src/2.6.7-1.437.1.ll.rhfc2.ccrma source tree
already ?
 
Using the stock kernel (from planet ccrma), I had an
issue with jackstart reporting no kernel real time
capabilities but jackd starting OK. Now with my custom
kernel, both jackd and jackstart work, qjackctl too.

Currently I still have the following issue: 
Non root user unable to start jackd/jackstart. 
With realcap loaded (at boot time) (installed realcap
script in init.d as you suggested)

[root@monstruo -lin_O_m]# lsmod | grep realcap
realcap                 4496  0
commoncap               4864  1 realcap
[invitado@monstruo invitado]$ jackstart --verbose -d

------------------------------------------------

I also have an issue with xmms and playing files
encoded at 44.1MHz with jack plugin. If I run jackd at
default rate of 48MHz then xmms and try to play file
encoded at 44.1, jack complains about xmms asking for
44.1MHz and jack running at 48. If I start hw:0 with
option -r 44100 (SB Live) then it does 44.1MHz.. But
the hw:1 (C-Media chipset) only does 48MHz even when
asked for 44.1MHz.  The hw:1 (C-Media chipset) will
only play files if original encoding was 48MHz

[root@monstruo -lin_O_m]# jackstart -R -d alsa -r

Apart from that it's cool. I could play one track
using jack and xmms in hw:0 sound card while using
alsaplayer to play to hw:1 at the same time. System is
very stable.
 
Well I think that's all for now. I found the whole
process much less difficult than with the older 2.4.2x
especially regarding real time support and patching
the kernel. It took me a few days of efforts to get
the kernel patched and jack working with the RH9 serie
. Here all is much more straightforward. Or maybe it's
just that I know a bit more what I'm doing ??? 

I don't know too much about the planet apps themselves
because I'm mainly interested in listening music, but
I really like what you do, if I can help you in
anything just let me know. Thanks.

Lionel.
