Priority: 7 Private: No Submitted By: IOhannes m zmlnig (zmoelnig) Assigned to: Miller Puckette (millerpuckette) Summary: [bugfix] for crasher bug when setting samplerate in alsa

Initial Comment: on my system (with an "nvidia CK804" onboard soundcard), i get immediate crashes if i select the plughw device (in Pd this shows up as "NVidia CK808 (plug-in)") with 44100Hz (the device only supports 48kHz) [1]

with the help of the alsa-developpers i hunted the problem down; it can be easily worked around if Pd was not using snd_pcm_hw_params_set_rate_min() (without setting a rate_max()) but snd_pcm_hw_params_set_rate_near() instead [2].

this patch does this (it's a one-liner) so now i can select all devices that show up in the media menu without having to fear a crash. (since it's a crasher, i raise the priority)

[1] i usually don't select plughw devices, so i haven't cared so much until now. but it's really annoying if you simply select a configuration in the preferences to make Pd crash)

[2] when alsa-devs were finally able to reproduce my problem, they simply asked "but why don't you just use rate_near()?"
