We are using LynxOne soundcard with OSS driver in digital mode with external clock option. We want to check the presense of Digital clock, before starting the audio process. Initially, we thought of using the input H/W buffer sample count to check that. But it does not work always. Sometime even with valid external clock, driver won't place any data in the hardware buffer even after few minutes. Did you come across this problem?
Also we have to delay the Timecode. We are not using MIDI feature. But time code comes only in MIDI port. Is it easy to change the timecode (LTC) in the MIDI stream? -----Original Message----- From: Paul Davis [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 19, 2002 7:16 AM To: [EMAIL PROTECTED] Subject: Re: [linux-audio-dev] Basic information >>> Hi.

In the meantime there's even a small primer, >how to open a sound device and make some noise. because its far from clear that this is the right thing to do with an SC port. if you don't know what SC is, you might not realize that the way 95% of all linux audio applications are written doesn't fit with SC's basic architectural model at all. many people think that writing a soundapp consists of opening a device, dumping some data to it and closing it. some programs can do that, but SC cannot. i don't know how much the questioner knows about the internal design of SC. its therefore not possible to answer the question until he pins down what he wants to do. --p _______________________________________________ linux-audio-dev mailing list [EMAIL PROTECTED] http://music.columbia.edu/mailman/listinfo/linux-audio-dev _______________________________________________ linux-audio-dev mailing list [EMAIL PROTECTED] http://music.columbia.edu/mailman/listinfo/linux-audio-dev
