Essentially, it's impossible to run `jackd` and `audacity` at the same time. If `jackd` is running, the embedded PortAudio library tries to probe `jackd` then falls on its face.

Actual Results: It crashed: see above. Expected Results: It should have worked as normal. Same result regardless of the value of the `jack` USE-flag. I tried building with USE=-jack to try and avoid that code path, `audacity` sees the JACK libs and builds against it anyway. Tried re-building portaudio (Audacity seems to bundle its own) and Audacity. Other software (e.g. Twinkle SIP client, PulseAudio) work fine with JACK.

Tried myself while jackd is running (jack2) with your .asoundrc. With USE="jack alsa" it did spit out similar warnings but still started fine (no assert messages), and with "jack -alsa" cleanly worked and using jackd directly. I don't use usbstream though, maybe related.
To the best of my knowledge, I'm not using `usbstream` either. (Why would I when there's `snd-usb-audio`?) I haven't tried with `alsa` disabled, I guess I'll try that next.
Created attachment 680332 [details] Clicking "rec" in Audacity Well the good news is with USE="-alsa jack", it does start… however, clicking "Record" has me confused!
So, a bit of digging around: audacity: ../common/JackGraphManager.cpp:48: void Jack::JackGraphManager::AssertPort(jack_port_id_t): Assertion `port_index < fPortMax' failed. audacity: ../common/JackGraphManager.cpp:48: void Jack::JackGraphManager::AssertPort(jack_port_id_t): Assertion `port_index < fPortMax' failed. Those two lines are emitted from this file: jack2-1.9.16/common/JackGraphManager.cpp: 44 void JackGraphManager::AssertPort(jack_port_id_t port_index) 45 { 46 if (port_index >= fPortMax) { 47 jack_log("JackGraphManager::AssertPort port_index = %ld", port_index); 48 assert(port_index < fPortMax); 49 } 50 } Clearly, fPortMax is smaller than expected, or port_index is above the set maximum. Question is, where do these values come from? fPortMax is set by the constructor: 66 JackGraphManager::JackGraphManager(int port_max) 67 { 68 assert(port_max <= PORT_NUM_MAX); 69 70 for (int i = 0; i < port_max; i++) { 71 fPortArray[i].Release(); 72 } 73 74 fPortMax = port_max; 75 } … which is called here: 52 JackGraphManager* JackGraphManager::Allocate(int port_max) 53 { 54 // Using "Placement" new 55 void* shared_ptr = JackShmMem::operator new(sizeof(JackGraphManager) + port_max * sizeof(JackPort)); 56 return new(shared_ptr) JackGraphManager(port_max); 57 } This seems to have just one caller, jack2-1.9.16/common/JackServer.cpp line 56: 43 //---------------- 44 // Server control 45 //---------------- 46 JackServer::JackServer(bool sync, bool temporary, int timeout, bool rt, int priority, int port_max, bool verbose, jack_timer_type_t clock, char self_connect_mode, const char* server_name) 47 { 48 if (rt) { 49 jack_info("JACK server starting in realtime mode with priority %ld", priority); 50 } else { 51 jack_info("JACK server starting in non-realtime mode"); 52 } 53 54 jack_info("self-connect-mode is \"%s\"", jack_get_self_connect_mode_description(self_connect_mode)); 55 56 fGraphManager = JackGraphManager::Allocate(port_max); … which is called in jack2-1.9.16/common/JackServerGlobals.cpp (line 55): 41 int JackServerGlobals::Start(const char* server_name, 42 jack_driver_desc_t* driver_desc, 43 JSList* driver_params, 44 int sync, 45 int temporary, 46 int time_out_ms, 47 int rt, 48 int priority, 49 int port_max, 50 int verbose, 51 jack_timer_type_t clock, 52 char self_connect_mode) 53 { 54 jack_log("Jackdmp: sync = %ld timeout = %ld rt = %ld priority = %ld verbose = %ld ", sync, time_out_ms, rt, priority, verbose); 55 new JackServer(sync, temporary, time_out_ms, rt, priority, port_max, verbose, clock, self_connect_mode, server_name); So, it could be a command line argument that previously didn't give problems, but is now tickling things the wrong way. I'm not sure though whether it is something `qjackctl` is passing `jackd` when it starts it (curiously, I can't even *see* `jackd` in the process tree even though it is clearly running) or whether Audacity is the guilty party at this point. PulseAudio also works via Jack, and there, I don't have problems. I have a week-daily session with work colleagues on Slack using jackd, and that works without a hitch. It's just Audacity that gives me problems, I'll have to see if it's Audacity itself or its version of PortAudio (since it seems to bring its own).

Okay… I got Audacity to start properly. - I could not find `jackd`, but did note that `jackdbus` was running. So, I killed it. (initially with -TERM, then -QUIT, finally -KILL when it didn't take the hint). - `pulseaudio` took great umbrage to this, spinning CPU wildly and gobbling RAM like crazy. So it too, got the `kill` treatment. - `pulseaudio` re-spawns. - I restart JACK via `qjackctl` for good measure. Now, Audacity starts, and seems to work. I think it might be a case of "turn it off, and back on again"… I shall keep an eye on this.
