I saw the -C switch (or arecord), but didn't try it because the examples I've seen had hardware input. It doesn't work though. A file gets created with a reasonable looking header, but all zeros where the data should be and it never stops, so I have to CTRL C. If I simply '>' the input, which was going to aplay, to a file, it's done in a flash. Unplayable, but the file contains data. Could I write a header first somehow? Or a container format would be OK. -- John. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx https://lists.linuxaudio.org/listinfo/linux-audio-user
