[Nyquist-users] problem with nyquist on fedora core 13

[<pr...@un...>]

I'm having a problem running the version of nyquist distributed with
fedora core 13.  This looks to be pretty close to the standard 3.03
distribution although there are changes to deal with relevant
libraries etc.
I've downloaded the source for the 
package
nyquist.x86_64                        3.03-3.fc12
and done a fair bit of digging.  The problem appears to be when
building the list of available output devices in pa_linux_alsa.c.
the function
 snd_pcm_open( &pcm, deviceNames[i].alsaName, SND_PCM_STREAM_PLAYBACK,  blocking )
fails (i.e returns negative) for the alsa device "hw,0,0"
which corresponds to the sound device
/dev/snd/pcmC0D0p.
One can confirm this using strace where one sees a line:
open("/dev/snd/pcmC0D0p", O_RDWR|O_NONBLOCK|O_CLOEXEC) = -1 EBUSY (Device or resource busy)
Now this is a bit odd. I *am* using the device already since I have a
speech synthesizer running but I can confirm I can open it again and
play other sounds in parallel e.g. with mpg123.  Confirmed with
strace -eopen -ooutfile mpg123 mytrack.mpe
open("/dev/snd/pcmC0D0p", O_RDWR|O_APPEND|O_NONBLOCK|O_CLOEXEC) = 4
No problem.
Note the extra "O_APPEND" flag here.
This is probably a portaudio question but I thought I'd ask here since
I'm not sure Roger is using the vanilla portaudio distribution.

Also can I ask what the current plans for development of the cvs
version are?  I can't compile that at the moment, the portaudio
subdirectory seems to be empty or nearly so.  Roger, ar you cutting
over to the standard portaudio distribution?
Thanks in advance for any help
cheers
Peter
