Corresponding<br>character devices are removed according to 'remove' callbacks of relevant<br>drivers from Linux dd core. Then the models re-appear on the bus by<br>generating bus resets and corresponding character devices are added<br>according to 'probe' callbacks from Linux dd core.<br><br>In a view of ALSA applications, this looks that plug-out/plug-in occur in<br>a sequential order for the models when they stop playback/capture substream.<br>For most applications, this doesn't cause large issue. However, this quirk<br>is not good for combination of below modules in PulseAudio. PulseAudio<br>enters endless loop to detect the models and start/stop PCM substream.<br> - module-udev-detect<br> - module-alsa-card<br> - module-suspend-on-idle<br><br>In detail, please read my comment no.6:<br>https://bugzilla.kernel.org/show_bug.cgi?id=199365#c6<br><br>This commit suppressed udev detection of sound card for the issued models.<br>For the models, 'PULSE_IGNORE' flag is added to udev rules, then<br>module-udev-detect don't handle the models and PulseAudio never uses the<br>models automatically. In a scenario for users to load<br>module-alsa-card/module-alsa-sink/module-alsa-source by hand, although<br>these modules can still stop PCM substreams with module-suspend-on-idle,<br>PulseAudio never enters the endless loop because udev detection doesn't<br>work for the models. In this case, as long as special files for ALSA<br>character devices for these models are the same, corresponding sinks and<br>sources are available even if the voluntary plug-out/plug-in occur.<br><br>(Focusrite Saffire Pro 10 i/o with systemd 237)<br>$ udevadm info -q all -p /devices/pci0000:00/0000:00:07.0/fw1/fw1.0/sound/card1<br>P: /devices/pci0000:00/0000:00:07.0/fw1/fw1.0/sound/card1<br>E: DEVPATH=/devices/pci0000:00/0000:00:07.0/fw1/fw1.0/sound/card1<br>E: ID_BUS=firewire<br>E: ID_FOR_SEAT=sound-pci-0000_00_07_0<br>E: ID_ID=firewire-0x00130e01000606e0<br>E: ID_MODEL=Pro10IO<br>E: ID_MODEL_FROM_DATABASE=XIO2213A/B/XIO2221 IEEE-1394b OHCI Controller [Cheetah Express]<br>E: ID_MODEL_ID=0x000006<br>E: ID_PATH=pci-0000:00:07.0<br>E: ID_PATH_TAG=pci-0000_00_07_0<br>E: ID_PCI_CLASS_FROM_DATABASE=Serial bus controller<br>E: ID_PCI_INTERFACE_FROM_DATABASE=OHCI<br>E: ID_PCI_SUBCLASS_FROM_DATABASE=FireWire (IEEE 1394)<br>E: ID_SERIAL=0x00130e01000606e0<br>E: ID_SERIAL_SHORT=0x00130e01000606e0<br>E: ID_VENDOR=Focusrite<br>E: ID_VENDOR_FROM_DATABASE=Texas Instruments<br>E: ID_VENDOR_ID=0x00130e<br>E: SOUND_INITIALIZED=1<br>E: SUBSYSTEM=sound<br>E: SYSTEMD_WANTS=sound.target<br>E: TAGS=:systemd:seat:<br>E: USEC_INITIALIZED=957089064<br><br>(Focusrite Saffire Pro 26 i/o with systemd 237)<br>$ udevadm info -q all -p /devices/pci0000:00/0000:00:07.0/fw1/fw1.0/sound/card1<br>P: /devices/pci0000:00/0000:00:07.0/fw1/fw1.0/sound/card1<br>E: DEVPATH=/devices/pci0000:00/0000:00:07.0/fw1/fw1.0/sound/card1<br>E: ID_BUS=firewire<br>E: ID_FOR_SEAT=sound-pci-0000_00_07_0<br>E: ID_ID=firewire-0x00130e0100030cdd<br>E: ID_MODEL=Pro26IO<br>E: ID_MODEL_FROM_DATABASE=XIO2213A/B/XIO2221 IEEE-1394b OHCI Controller [Cheetah Express]<br>E: ID_MODEL_ID=0x000003<br>E: ID_PATH=pci-0000:00:07.0<br>E: ID_PATH_TAG=pci-0000_00_07_0<br>E: ID_PCI_CLASS_FROM_DATABASE=Serial bus controller<br>E: ID_PCI_INTERFACE_FROM_DATABASE=OHCI<br>E: ID_PCI_SUBCLASS_FROM_DATABASE=FireWire (IEEE 1394)<br>E: ID_SERIAL=0x00130e0100030cdd<br>E: ID_SERIAL_SHORT=0x00130e0100030cdd<br>E: ID_VENDOR=Focusrite<br>E: ID_VENDOR_FROM_DATABASE=Texas Instruments<br>E: ID_VENDOR_ID=0x00130e<br>E: SOUND_INITIALIZED=1<br>E: SUBSYSTEM=sound<br>E: SYSTEMD_WANTS=sound.target<br>E: TAGS=:systemd:seat:<br>E: USEC_INITIALIZED=1071026684<br><br>Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp></p> </td> </tr> </table> </td> </tr> </table> </td> </tr>  <tr> <td id="system-message-section" align="center" valign="top" style="padding-bottom:20px;padding-bottom: 20px;"> <table id="system-message-container" border="0" cellpadding="0" cellspacing="0" style="width:500px;padding:32px;background-color:#FFFFFF;border:1px solid #0068FF;border-radius:3px;width: 500px; padding: 32px; background-color: #FFFFFF; border: 1px solid #0068FF; border-radius: 3px;"> <tr> <td id="broadcast-logo-section" align="center" valign="top"> <div class="system-message-item" style="padding-bottom: 32px;"> <img alt="broadcast tower image" id="system-message-logo" src="https://s3.amazonaws.com/travis-email-assets/system_message.png" style="width:20px;height:auto;vertical-align:sub;padding-right:8px;padding-right: 8px; width: 20px; height: auto; vertical-align: sub;"> <h2 id="system-message-header" style="font-size:24px;display:inline;font-weight:300;color:#0068FF;margin:0px;display: inline; font-size: 24px; font-weight: 300; color: #0068FF; margin: 0px;">System Message</h2> </div> <div> <img alt=" broadcast indicator" class="broadcast-category-icon" src="https://s3.amazonaws.com/travis-email-assets/warning_dot.png" style="float:left;width:11px;height:auto;margin-right:10px;padding-top:7px;width: 11px; height: auto; float: left; margin-right: 10px; padding-top: 7px;"> </div> <div> <p class="broadcast-message" style="margin:0px;max-width:85%;font-size:16px;font-weight:300;text-align:left;line-height:26px;border-bottom:1px solid #DCDFE2;padding-bottom:20px;margin-bottom:20px;font-size: 16px; line-height: 26px; font-weight: 300; text-align: left; max-width: 85%; border-bottom: 1px solid #DCDFE2; padding-bottom: 20px; margin-bottom: 20px;">We have changed our default macOS/OS X image to be Xcode 9.4!
