cannot detect modem on HDA bus =========== hda - as a hub through which can be connected many devices (audio and modem - which I know) linux determined in all possible devices that are connected to hda BSD made in the implementation wrong, because in many places there are special control points to check - what this device. And if this does not sound - it is ignored that is - not universally hence - Ariff only knows how to implement it hda code to add a modem ============ see patch for detect all HDA devices on my machine I have sound and modem: pcm0: HDA_DEBUG: Scanning HDA codecs [start index=0] ... pcm0: HDA_DEBUG: Probing codec: 0 pcm0: HDA_DEBUG: startnode=1 endnode=2 pcm0: Vendor: 0x10ec0883 pcm0: HDA_DEBUG: Found AFG nid=1 [startnode=1 endnode=2] pcm0: HDA_DEBUG: Probing codec: 1 pcm0: HDA_DEBUG: startnode=2 endnode=3 pcm0: Vendor: 0x14f12bfa pcm0: HDA_DEBUG: AFG not found pcm0: HDA_DEBUG: Probing codec: 3 pcm0: hdac_command_send_internal: TIMEOUT numcmd=1, sent=1, received=0 pcm0: hdac_command_send_internal: TIMEOUT numcmd=1, sent=1, received=0 pcm0: hdac_command_send_internal: TIMEOUT numcmd=1, sent=1, received=0 pcm0: HDA_DEBUG: startnode=255 endnode=510 pcm0: Vendor: 0xffffffff Fix: rewrite HDA Patch attached with submission follows: How-To-Repeat: always

I have a laptop with built modem. But it is not defined at boot time. Also, it is not visible in the list pciconf-lv. On how much I learned modem located on the bus hda. I would like to use the modem to work, so I ask the developer to finalize the driver hda to work correctly with other devices except for the sound card. When using a patch to hda I managed to see the modem, but to use it, I could not.
Hi. We can treat a modem codec as one of the "function group" like the audio function group. But almost all the structure of the modem function group is vendor specific. To control the modem codec, we have to obtain the codec's specifications. But I don't know a manufacturer which offers HDA modem codec's datasheets. So it is hard for us to write these codec's device driver. Listing a modem codec in a verbose dmesg is not so an important matter (because we cannot use it now). FYI, last year I tried to port the "slmodemd" daemon which supports several number of modem codecs on Linux with the ALSA driver. http://homepage2.nifty.com/dumb_show/unix/slmodemd-FreeBSD.en.html I could get some responses from the modem codec. It generated sound which was similar to a dialing and negotiation tone. But I could not use it as a modem at all. --- WATANABE Kazuhiro (CQG00620@nifty.ne.jp)
State Changed From-To: open->suspended Latest snd_hda driver detects/reports all present codecs. But due to lack of codec specifications, modem support implementation looks very problematic.
batch change: For bugs that match the following - Status Is In progress AND - Untouched since 2018-01-01. AND - Affects Base System OR Documentation DO: Reset to open status. Note: I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed.
