| * | rules: identify internal sound cards on platform bus (#4893) | Daniel Drake | 2016-12-15 | 1 | -0/+7 |
| | | | | | | | | | | | | | | | | | | | | | | | | | We have a system which has the HDMI audio capability internally, but pulseaudio is not giving it a very high priority compared to e.g. USB sound cards. The sound device appears on the platform bus and it is not currently tagged with any form factor information. It seems safe to assume that any sound card that is directly on the platform bus is of internal form factor, but we must be careful because udev rules will match all parent devices, not just the immediate parent, and you will frequently encounter setups such as: Platform bus -> USB host controller -> USB sound card In that case, SUBSYSTEMS==platform would match even though we're clearly working with an external USB sound card. In order to detect true platform devices here, we rely on the observation that if any parent devices of the sound card are PCI, USB or firewire devices, then this sound card cannot directly connected to the platform bus. Otherwise, if we find a parent device on the platform bus, we assume this is an internal sound card connected directly to the platform bus. | ||||
| * | rules: Add more firewire properties for sound, to be closer to USB and PCI | Adam Goode | 2015-04-23 | 1 | -3/+6 |
| | | | | | | | | | | USB and PCI soundcards have a nice set of ID_* properties. It would be handy for firewire soundcards to have the same. Note that this removes the explicit setting of ID_ID in the firewire conditional. Because we are now setting ID_SERIAL, ID_ID will come from later in the file. | ||||
| * | rules: Don't use ALSA card id in ID_ID | Adam Goode | 2015-04-23 | 1 | -2/+2 |
| | | | | | | | | | | | | | | | | | | The ALSA id sysattr is generated by the sound subsystem and is not a stable identifier. It is generated though some string manipulation then made unique if there is a conflict. This means that it is enumeration-dependent and shouldn't be used for ID_ID. If ID_ID is supposed to be system-unique, it is not already since for firewire it is generated from the guid and there are broken firewire devices that have duplicate guids across devices. This is tracked for PulseAudio at https://bugs.freedesktop.org/show_bug.cgi?id=90129. This is essentially a revert of systemd ed1b2d9fc7d5c5bfe2a67b0b8ff9e5ea8694268e. | ||||
