Red Hat Bugzilla – Bug 850553
Add key/value for audio codec to beaker
Last modified: 2016-05-26 09:13:39 EDT
Description of problem: Enhancment request to provide the audio codex as a key/value. The /proc/asound/cardX directory contains the codec product information that would be very helpful if Beaker allowed user searches for it. Version-Release number of selected component (if applicable): N/A How reproducible: Always Steps to Reproduce: 1. None 2. 3. Actual results: Which to search for which have the ATI R6xx codex onboard. Expected results: None Additional info: None

I would like to raise the priority on this request as automation is impacted by not being able to get the information from our system base.
We're postponing this one until we can migrate the inventory task from smolt to lshw, rather than adding more features to the existing smolt based implementation that we will just have to replicate with lshw later.
Can you just use PCI device id and/or subsystem id to identify the cards you need? I'm not sure how to fit the AC97 and HDA "codecs" into Beaker's current device model, which considers each device to be essentially just a tuple of (bus, driver, pciid, subsysid, description).
My workstation has an onboard Intel HDA, but it also has this second sound card, I guess on the GPU: 0f:00.1 Audio device [0403]: NVIDIA Corporation GF108 High Definition Audio Controller [10de:0bea] (rev a1) Subsystem: Hewlett-Packard Company Device [103c:0835] According to alsa, this card has *four* codecs, all of which are: Codec: Nvidia GPU 14 HDMI/DP Vendor Id: 0x10de0014 Subsystem Id: 0x10de0101 If a single sound card has multiple codecs, can we assume they are all the same? Maybe the answer is to treat the audio codecs as separate devices in themselves, and report them in addition to the sound cards themselves. So in this case I would have: (NVIDIA Corporation GF108 High Definition Audio Controller, 10de, 0bea, 103c, 0835) (Nvidia GPU 14 HDMI/DP, 10de, 0014, 10de, 0101) (Nvidia GPU 14 HDMI/DP, 10de, 0014, 10de, 0101) (Nvidia GPU 14 HDMI/DP, 10de, 0014, 10de, 0101) (Nvidia GPU 14 HDMI/DP, 10de, 0014, 10de, 0101) ... plus the Intel HDA and its codecs.
Each codec has it's own address on the HDA serial bus: $ cat /proc/asound/card0/codec#0 Codec: Intel Haswell HDMI Address: 0 ^^^^^^^^^^ So the codecs are like addressable components. I would add this address to the full component identifier.
