How about snd_emu10kx ? There are still few pending fixes that need to be applied for snd_emu10kx (Yuriy Tsibizov is the current maintainer for this driver) I'm particularly interested in [1] (need a serious double blind test to rule out placebo effect caused by hearing tardiness) and [4] (specific driver issue). Thanks for your effort on doing various of these tests. > Relevant sysctl output as of now: > % sysctl -a | egrep 'snd|pcm' > hw.snd.latency_profile: 1 > hw.snd.latency: 5 > hw.snd.report_soft_formats: 1 > hw.snd.feeder_buffersize: 16384 > hw.snd.feeder_fmt_downmix: 0 > hw.snd.feeder_rate_round: 25 > hw.snd.feeder_rate_max: 2016000 > hw.snd.feeder_rate_min: 1 > hw.snd.verbose: 1 > hw.snd.sndstat_isopen: 0 > hw.snd.maxautovchans: 4 > hw.snd.default_unit: 0 > dev.pcm.0.%desc: Creative EMU10K1 > dev.pcm.0.%driver: pcm > dev.pcm.0.%location: slot=10 function=0 > dev.pcm.0.%pnpinfo: vendor=0x1102 device=0x0002 subvendor=0x1102 > subdevice=0x8061 class=0x040100 dev.pcm.0.%parent: pci0 > dev.pcm.0.eapd: 1 > dev.pcm.0.buffersize: 4096 > dev.pcm.0.vchans: 1 > dev.pcm.0.vchanrate: 48000 > dev.pcm.0.vchanformat: s16le > > % kldstat > Id Refs Address Size Name > 1 15 0xc0400000 691928 kernel > 2 2 0xc0a92000 1aff0 linux.ko > 3 1 0xc0aad000 71ac snd_emu10k1.ko > 4 3 0xc0ab5000 3c330 sound.ko > 5 1 0xc0af2000 4a59d4 nvidia.ko > 6 1 0xc0f98000 58554 acpi.ko > 7 1 0xc3a8e000 e000 ext2fs.ko > 8 1 0xc3bd0000 2000 blank_saver.ko > > > Hope that helps. :) > > Regards. > > ps: please keep me in Cc: as I'm not subscribed to multimedia@. > -- Ariff Abdullah FreeBSD ...
