I'm the author of that page. I wasn't aware of mtrx, but it seems to be a fork of my original trx code, but with all the original attribution removed, a bit of obfuscation through reformatting, and a new license. > Anyway, I also tried trx when I ran into the issue I'm about to > describe, but the 'rx' program segfaulted when I sent the stream, so > that's probably not going to work. If you're trying to interchange streams between the two applications then this is unlikely to work; though a segfault is unexpected. I can state that trx does work; I use it every day in this manner. If you can paste the exact output from trx (not mtrx) including the buffer underrun then I might be able to help guide you to which parameter needs changing, but it's likely to just be the ALSA buffer size. Make sure you are running with the correct realtime priorities if you want low latency. -- Mark _______________________________________________ Alsa-user mailing list Alsa-user@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-user
