This might be related to your latency problem. What sound card are you using? That will have an impact on the latency results. e.g. the ALSA driver for my ymf744 sends latency through the roof (~30ms); if I use the OSS driver that comes with the kernel, it's ~5ms. But anyway, hearing crackling is a bad sign. I don't know anything about the ALSA version of the latency test, but are your OSS results good? Try using the OSS version of latencytest along with ALSA's snd-pcm-oss emulation module. If you get good results with that, it'll be the ALSA library or the ALSA functions in the latencytest programs which are screwing up, not your system. -- #ozone/algorithm <[EMAIL PROTECTED]> - trust.in.love.to.save _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
