Also what's the exact bug symptom? Many people reported this on various mailing lists, but I'm not aware of any bugzilla/whatever ticket. Problem seems to be that ALSA/OSS does not report the true HW sampling rate, but tries to do the sample rate conversion by itself, but apparently not doing it good enough for modem type applications. Anyway I find it not a good idea of alsa to try to do sample rate conversion in kernel for OSS, as the native OSS drivers never did this, and it is useless for software (like soundmodem) that tries to find out the hardware rates in order to adapt to them. Kernel resampling badly interferes with this. Tom PS: I was too lazy to investigate this in depth, it was easier to just add a native ALSA driver to soundmodem. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
