leonardusI haven't been paying attention, is there a release date for 18.10 yet?14:37
=== not_phunyguy is now known as phunyguy
RouninTJ-: Seems that my other user, Mr. Guest Guest, also has the same issue20:39
TJ-Rounin: ok, that helps a lot20:39
TJ-so as pacmd also doesn't list it it seems to be a problem with PA finding the ALSA devices. I think the next thing to do is test the ALSA output to prove there is sound20:40
TJ-Rounin: can you show me "pastebinit <( aplay -L )"20:40
RouninOutright moving .config/pulse and killall -9 pulse had no effect either20:41
RouninTJ-: What a clever tool! http://paste.ubuntu.com/p/ShfRg6Ggyw/20:42
Rounin(Now all we need to do is build a network stack on top of it, and we can finally have functional bidirectional TCP again)20:42
TJ-Rounin: now try "speaker-test -Dfront:CARD=PCH -t wav"20:46
RouninTJ-:  Hmmm... "Playback open error: -16,Device or resource busy"20:48
RouninTJ-: And aplay with -D sysdefault led to: ALSA lib pcm_dmix.c:1063:(snd_pcm_dmix_open) unable to create IPC semaphore aplay: main:828: audio open error: Permission denied20:48
Rouninfront:CARD=PCH seems to lead to "Device or resource busy" whereas sysdefault:CARD=PCH gets permission denied when creating the semaphore20:52
RouninI was so sure we could blame Poettering for this one20:52
TJ-Rounin: I think I had the syntax slightly wrong; but I can't make it work here either - I suspected in my case PA had thw ALSA device open exclusively. The syntax should be "-Dfront:PCH -t wav"20:53
RouninAh wait wait20:53
RouninNow I tried it as root20:54
RouninLet me just move my cable over to the analogue port20:54
Rounin"left front left front..."20:55
RouninYeah, seems like it's just a permission issue20:55
RouninIf only I knew what to change the permissions of... Do you know where these devices are?20:55
TJ-Right, so maybe your user isn't in the plugdev and/or audio groups?20:57
RouninThere are some "pulse" and "audio" gr... Yup20:57
RouninPerhaps I did something weird to make it work before, and it stopped working due to the upgrade?20:58
RouninCan't imagine why it worked in the previous version20:58
TJ-Rounin: have you reviewed the syslog/auth.log for clues ?20:59
RouninTJ-: Oh wow! A lot of "Oct  6 17:53:30 lightning dbus-daemon[846]: [system] Rejected send message, 1 matched rules; type="error", sender=":1.42" (uid=1000 pid=2144 comm="/usr/bin/pulseaudio --start --log-target=syslog " label="unconfined") interface="(unset)" member="(unset)" error name="org.bluez.MediaEndpoint1.Error.NotImplemented" requested_reply="0" destination=":1.299" (uid=0 pid=8035 comm="/usr/lib/bluetooth/bluetoothd " 21:00
Rouninlabel="unconfi"21:00
RouninEtc. etc.21:00
RouninI've added myself to the groups, so I'll try logging out entirely and then back in21:01
RouninBrb21:01
RouninHello again! I had to go in with a bootable USB and change my root password... Apparently I misspelled it when I set it, and the next 5-6 times I typed it21:15
RouninAnyway, TJ-, I just wanted to say it's working now, and it was indeed the pulseaudio/audio/etc. group issue. Thanks so much for your help!21:15
TJ-Rounin: yay! I wonder if that needs reporting since it seems it should have been handled in the upgrade21:16
RouninTJ-: Yeah, hard to tell... After all, who knows how and why it was working before?21:17
