I'm using Gentoo and I know /etc/asound.conf works because defining dmix's sample rate there lights up the corresponding LED on the USB DAC. I tried moving the config to ~/.asoundrc with no change. > Nevertheless, I guess these "static" problem is not related > to the resample algorithm you are using - unless the problem > is related to insufficient system resources.

When I bypass dmix in mpd there is no static, and when I don't there is static, so I don't think it's performance related. > I say this 'cause e.g. with my old laptop (PIIIM 1.2GHz) > basically I could not use anything better than the default. > Trying just about any other algorithm caused problems such > as underruns, skips, errors, etc. > > Assuming this is not your case, your "static" problem may > be due to inappropriate sample rate and/or format of the > data sent to the sound card.

I've lit up all 4 frequency LEDs on the DAC and they all have static when dmix is involved. I still think the static problem is due to dmix's default resampling algorithm. I haven't seen any evidence that my defaults.pcm.rate_converter is being obeyed. With it set to "samplerate_best" I get the same 'lsof|grep aplay' output I posted before. There is no mention of libsamplerate or speex and there is static in the sound produced by aplay. - Grant ------------------------------------------------------------------------------ The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
