Update: - When I tell audacity to use ALSA directly instead of OSS emulation, it doesn't hang anymore. But the cursor doesn't start. - When I also tell audacity to use software playthrough, it seems to start recording. But it records only silence. In every case, arecord still hangs at the header of 44 bytes. Any hint? m. -- gentoo-user@gentoo.org mailing list
