Hello everyone, I've installed FreeBSD 10 RELEASE on my Dell XPS 14z. However, the sound system doesn't work correctly. Could anyone here help me to tell me what's the problem? Thanks in advance. Output of '% cat /dev/sndstat': Installed devices: pcm0: <Realtek> (play/rec) default pcm1: <Intel> (play) Output of '% dmesg | grep pcm' pcm0: <Realtek> at nid 20,33 and 18 on hdaa0 pcm1: <Realtek> at nid 24 on hdaa0 pcm2: <Intel> at nid 5 on hdaa1 pcm0: <Realtek> at nid 20,33 and 18 on hdaa0 pcm1: <Realtek> at nid 24 on hdaa0 pcm2: <Intel> at nid 5 on hdaa1 pcm0: <Realtek> at nid 20,33 and 18 on hdaa0 pcm1: <Realtek> at nid 24 on hdaa0 pcm2: <Intel> at nid 5 on hdaa1 pcm0: <Realtek> at nid 20,33 and 18 on hdaa0 pcm1: <Realtek> at nid 24 on hdaa0 pcm2: <Intel> at nid 5 on hdaa1 pcm0: <Realtek> at nid 20,33 and 18 on hdaa0 pcm1: <Realtek> at nid 24 on hdaa0 pcm2: <Intel> at nid 5 on hdaa1 pcm0: <Realtek> at nid 20,33 and 18 on hdaa0 pcm1: <Realtek> at nid 24 on hdaa0 pcm2: <Intel> at nid 5 on hdaa1 pcm0: <Realtek> at nid 24 on hdaa0 pcm1: <Intel> at nid 5 on hdaa1 pcm0: <Realtek> at nid 33 and 24 on hdaa0 pcm1: <Intel> at nid 5 on hdaa1 Output of '% sudo sysctl hw.snd': hw.snd.report_soft_formats: 1 hw.snd.report_soft_matrix: 1 hw.snd.latency: 5 hw.snd.latency_profile: 1 hw.snd.vpc_autoreset: 1 hw.snd.vpc_0db: 45 hw.snd.vpc_reset: 0 hw.snd.compat_linux_mmap: 0 hw.snd.feeder_eq_presets: PEQ:16000,0.2500,62,0.2500:-9,9,1.0:44100,48000,88200,96000,176400,192000 hw.snd.feeder_eq_exact_rate: 0 hw.snd.feeder_rate_presets: 100:8:0.85 100:36:0.92 100:164:0.97 hw.snd.feeder_rate_polyphase_max: 183040 hw.snd.feeder_rate_min: 1 hw.snd.feeder_rate_max: 2016000 hw.snd.feeder_rate_round: 25 hw.snd.feeder_rate_quality: 1 hw.snd.vpc_mixer_bypass: 1 hw.snd.verbose: 0 hw.snd.default_auto: 0 hw.snd.version: 2009061500/amd64 hw.snd.default_unit: 0 hw.snd.maxautovchans: 16 Output of '% sudo sysctl dev.pcm' dev.pcm.0.%desc: Realtek ALC269 (Right Analog) dev.pcm.0.%driver: pcm dev.pcm.0.%location: nid=33,24 dev.pcm.0.%parent: hdaa0 dev.pcm.0.play.vchans: 3 dev.pcm.0.play.vchanmode: fixed dev.pcm.0.play.vchanrate: 48000 dev.pcm.0.play.vchanformat: s16le:2.0 dev.pcm.0.play.32bit: 24 dev.pcm.0.rec.vchans: 1 dev.pcm.0.rec.vchanmode: fixed dev.pcm.0.rec.vchanrate: 48000 dev.pcm.0.rec.vchanformat: s16le:2.0 dev.pcm.0.rec.32bit: 24 dev.pcm.0.rec.autosrc: 2 dev.pcm.0.buffersize: 65536 dev.pcm.0.bitperfect: 0 dev.pcm.1.%desc: Intel Cougar Point (HDMI/DP 8ch) dev.pcm.1.%driver: pcm dev.pcm.1.%location: nid=5 dev.pcm.1.%parent: hdaa1 dev.pcm.1.play.vchans: 1 dev.pcm.1.play.vchanmode: passthrough dev.pcm.1.play.vchanrate: 48000 dev.pcm.1.play.vchanformat: s16le:2.0 dev.pcm.1.play.32bit: 24 dev.pcm.1.buffersize: 65536 dev.pcm.1.bitperfect: 0 And I don't know how to config the /boot/device.hint. According to the instruction, (https://forums.freebsd.org/viewtopic.php?&t=30502) ,I try appending the following 2 lines to the file and reboot, but it doesn't work: hint.hdaa.0.nid18.config="as=5 seq=0 device=Speaker" hint.hdaa.0.nid20.config="as=5 seq=15 device=Headphones" Could anyone here tell me how to correctly config my laptop's sound system? Any suggestion will be appreciated. -- Levski Weng
