i welcome as many drivers as people can provide, on the understanding that they will not necessarily be maintained by anyone except the contributor, and if the internal API changes (as has happened between 0.80 and 0.90) and the driver is not ported, it will be removed from the Makefiles. --p

what kinds of features are you thinking of? most of the hardware-related features derive from the ALSA driver, not JACK itself. that would be fine with me. we can package jack-audio-connection-kit with just the core supported drivers (whatever they may be) and then jack-audio-connection-kit-<foo> for other drivers. its a trivial change to the Makefiles that i know taybin will love to do :) --p

I suspect things would probably work differently using one of the "real" OSS driver implementations. One helpful thing you could do would be testing it on a system with a real OSS driver. Running this version on my M-Audio Delta-66 card, I see... Name = /dev/dsp Max Inputs = 16 Max Outputs = 16 Sample Rates = 48000.00, 44100.00, 32000.00, 24000.00, 22050.00, 16000.00, 11025.00, 8000.00, Native Sample Formats = paUInt8, paInt16, If I try to set the sample rate to 88200, it fails... Pa_SetupDeviceFormat: HW does not support 88200 Hz sample rate Using the ALSA interface, the same card supports 24-bit in 32-bit and 96 kHz. I don't know whether these differences are due to the driver, to PA, or to OSS. As I said, running this driver on Linux is very immature, yet. I don't think so. Should it? Do you mean the JACK driver or the library? The JACK driver was originally written for MacOSX. The current JACK driver is a straightforward backport from MacOSX to Linux. That was easy to do, so I am impressed with the "portable" aspect of PortAudio. It uses PortAudio version 18, which is the current release level. A newer version 19 is currently in development but still not supported on MacOSX (IIUC). On Linux, PA V18 uses only the OSS drivers. V19 will also support ALSA and JACK client interfaces. This is helpful for writing portable applications, but not especially important for the JACK server. We already have an ALSA driver, and the idea of the JACK server running as a client of another JACK server is probably only interesting to mathematicians and computer scientists. ;-) We would like to use PA V19 too, of course. That would be a useful patch that someone could contribute. It will continue to be necessary for some time to support V18 as well. Probably, this should be conditionally compiled based on checking library function names in `configure.in'. -- joq
