Having used gusclassic & interwave drivers for a couple of years, some oddities bug me quite a bit: snd-synth-gus has existed for ages, yet I haven't heard of any method for loading patches and/or using rom ones. Is there a way to actually use the synth in not-so-100%-silent way? [using pmidi or other alsa-native methods, oss is boring]
Yesterday I got two unable-to-handle-kernel-paging-rq killing-interrupt- handler Oops's where stack contained pointers to alsa's address space... but those were with 2.4.18 + 0.9.0beta10 so debugging them is most likely waste of time, let's see if those happen again with more recent drivers... I haven't tested the external midi side of things as I have no eq for that. And then the DSP side: Killing sound apps (ctrl-c, kill -9, ...) seems to (randomly) cause noticeable hiss on left/right channel - I actually recorded it for ppl who want proof - http://www.hut.fi/u/iheino/hiss/ - silent.wav is record of no output, right.wav is playback of silent.wav recorded. I'm not certain whether "normal" buffer underruns cause hiss too but I think they might... To get rid of that noise I usually need to power-cycle the 'puter (unloading drivers, reinitializing pnp & reloading doesn't help) - nor does the following trick from NetBSD manual pages: guspnp(4) NetBSD Programmer's Manual guspnp(4) BUGS Sometimes you can cause a hiss on either left or right channel, or both. You can usually make it disappear by playing random data, however this might not be a very nice thing to your audio equipment, but it is the on- ly way I have found out to be effective. After thinking about it a bit I realized that the ISA bus has only soundcards on it... is resetting the entire ISA bus possible? ;) _______________________________________________ Alsa-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-user
