7.3.3.15 Pin Sense The Pin Sense control returns the Presence Detect status, EDID-Like Data (ELD) Valid, and the impedance measurement of the device attached to the pin. Some codecs may require that the impedance measurement be triggered by software; in that case, sending the Execute command will cause the impedance measurement to begin. The “Presence Detect” bit will always be accurate if that functionality is supported by the widget. Note that the Pin Complex Widget may support the generation of an Unsolicited Response to indicate that the Sense Measurement (either the Presence Detect or the Impedance) value has changed, the generation of which implies that the measurement is complete.
Impedance returns the measured impedance of the widget. A returned value of 0x7FFF,FFFF (all 1‟s) indicates that a valid sense reading is not available, or the sense measurement is busy (refer to Section 7.3.1) if it has been recently triggered. This field is only valid if the widget has Sense capability as indicated by the “Impedance Sense Capable” bit of the Pin Capabilities parameter. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1540372 Title: [Intel DP35DP, SigmaTel STAC9271D, Green Speaker, Rear] Underruns, dropouts or crackling sound Status in alsa-driver package in Ubuntu: Incomplete Bug description: I cant record or play on my sound card ubuntu 14.04.1 Alsa is detecting the sound card **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: STAC9271D Analog [STAC9271D Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: STAC9271D Digital [STAC9271D Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 but PulseAudio is not detecting the card attached the log file Thank you ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: alsa-base 1.0.25+dfsg-0ubuntu4 ProcVersionSignature: Ubuntu 3.19.0-47.53~14.04.1-generic 3.19.8-ckt10 Uname: Linux 3.19.0-47-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.19 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: tuned 1851 F.... pulseaudio CurrentDesktop: Unity Date: Mon Feb 1 15:09:35 2016 InstallationDate: Installed on 2015-10-26 (98 days ago) InstallationMedia: Ubuntu 14.04.3 LTS "Trusty Tahr" - Beta amd64 (20150805) PackageArchitecture: all SourcePackage: alsa-driver Symptom: audio Symptom_AlsaPlaybackTest: ALSA playback test through plughw:Intel failed Symptom_Card: Built-in Audio - HDA Intel Symptom_Jack: Green Speaker, Rear Symptom_Type: Underruns, dropouts, or "crackling" sound Title: [, SigmaTel STAC9271D, Green Speaker, Rear] Underruns, dropouts or crackling sound UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 10/02/2007 dmi.bios.vendor: Intel Corp. dmi.bios.version: DPP3510J.86A.0293.2007.1002.1519 dmi.board.asset.tag: Base Board Asset Tag dmi.board.name: DP35DP dmi.board.vendor: Intel Corporation dmi.board.version: AAD81073-207 dmi.chassis.type: 2 dmi.modalias: dmi:bvnIntelCorp.:bvrDPP3510J.86A.0293.2007.1002.1519:bd10/02/2007:svn:pn:pvr:rvnIntelCorporation:rnDP35DP:rvrAAD81073-207:cvn:ct2:cvr: mtime.conffile..etc.modprobe.d.alsa.base.conf: 2016-01-29T17:09:52.179523 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1540372/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
