Hi While sound work out of the box (with headphone switching) on the 1-2 year older Latitude 7270, it does not on my new machine. The internal speaker works fine. If I plug in external speakers in the headphone jack, sound still goes to the internal speaker while a very load buzz comes from the external speakers. Do we have a solution for this? # cat /dev/sndstat Installed devices: pcm0: <Realtek ALC256 (Internal Analog)> (play/rec) default pcm1: <Realtek ALC256 (Front Analog Headphones)> (play) pcm2: <Intel Kabylake (HDMI/DP 8ch)> (play) No devices installed from userspace. # sysctl hw.snd hw.snd.maxautovchans: 16 hw.snd.default_unit: 0 hw.snd.version: 2009061500/amd64 hw.snd.default_auto: 1 hw.snd.verbose: 0 hw.snd.vpc_mixer_bypass: 1 hw.snd.feeder_rate_quality: 1 hw.snd.feeder_rate_round: 25 hw.snd.feeder_rate_max: 2016000 hw.snd.feeder_rate_min: 1 hw.snd.feeder_rate_polyphase_max: 183040 hw.snd.feeder_rate_presets: 100:8:0.85 100:36:0.92 100:164:0.97 hw.snd.feeder_eq_exact_rate: 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.basename_clone: 1 hw.snd.compat_linux_mmap: 0 hw.snd.syncdelay: -1 hw.snd.usefrags: 0 hw.snd.vpc_reset: 0 hw.snd.vpc_0db: 45 hw.snd.vpc_autoreset: 1 hw.snd.timeout: 5 hw.snd.latency_profile: 1 hw.snd.latency: 5 hw.snd.report_soft_matrix: 1 hw.snd.report_soft_formats: 1 # sysctl dev.pcm dev.pcm.2.bitperfect: 0 dev.pcm.2.buffersize: 65536 dev.pcm.2.play.vchanformat: s16le:2.0 dev.pcm.2.play.vchanrate: 48000 dev.pcm.2.play.vchanmode: passthrough dev.pcm.2.play.vchans: 1 dev.pcm.2.play.32bit: 24 dev.pcm.2.%parent: hdaa1 dev.pcm.2.%pnpinfo: dev.pcm.2.%location: nid=3 dev.pcm.2.%driver: pcm dev.pcm.2.%desc: Intel Kabylake (HDMI/DP 8ch) dev.pcm.1.bitperfect: 0 dev.pcm.1.buffersize: 65536 dev.pcm.1.play.vchanformat: s16le:2.0 dev.pcm.1.play.vchanrate: 48000 dev.pcm.1.play.vchanmode: fixed dev.pcm.1.play.vchans: 1 dev.pcm.1.play.32bit: 24 dev.pcm.1.%parent: hdaa0 dev.pcm.1.%pnpinfo: dev.pcm.1.%location: nid=33 dev.pcm.1.%driver: pcm dev.pcm.1.%desc: Realtek ALC256 (Front Analog Headphones) dev.pcm.0.bitperfect: 0 dev.pcm.0.buffersize: 65536 dev.pcm.0.rec.vchanformat: s16le:2.0 dev.pcm.0.rec.vchanrate: 48000 dev.pcm.0.rec.vchanmode: fixed dev.pcm.0.rec.vchans: 1 dev.pcm.0.rec.autosrc: 2 dev.pcm.0.rec.32bit: 24 dev.pcm.0.play.vchanformat: s16le:2.0 dev.pcm.0.play.vchanrate: 48000 dev.pcm.0.play.vchanmode: fixed dev.pcm.0.play.vchans: 2 dev.pcm.0.play.32bit: 24 dev.pcm.0.%parent: hdaa0 dev.pcm.0.%pnpinfo: dev.pcm.0.%location: nid=20,18 dev.pcm.0.%driver: pcm dev.pcm.0.%desc: Realtek ALC256 (Internal Analog) dev.pcm.%parent:
