[17:43] Hi
[17:43] https://bpaste.net/show/93a7007ad2df
[17:44] pulseaudio -k only kills pulseaudio temporarily in the common case
[17:45] any pulseaudio client will respawn it nearly immediately
[17:45] you want to configure this client.conf->autospawn = no
[17:46] then pulseaudio wont respawn and you dont need pasupender
[17:46] == lpil_ [5c079cfd@gateway/web/freenode/ip.92.7.156.253] has quit [Ping timeout: 260 seconds]
[17:46] Oh yes, it is running I see
[17:47] Do I need to do anything to get /etc/pulse/client.conf to be read?
[17:49] nope
[17:49] just kill pulseaudio and it wont be spawned
[17:49] always check after the fact, its good practive
[17:50] https://bpaste.net/show/ef68c5b932c2
[17:50] For sure
[17:50] I guess that error means it got past the format error and now gives us a more generic error
[17:51] change the plugin from hw: to plughw: and see what happens
[17:51] I'll have it do both
[17:51] Seeing as it already loops
[17:52] https://bpaste.net/show/d70c49a9a28c
[17:52] good thinking
[17:52] last hail mary comment out --disable-format
[17:54] I just noticed that you have multiple instances of snd_usb_audio in the alsa-info.sh report that doesn't seem right
[17:55] https://bpaste.net/show/22b16c32d6a5
[17:55] What is snd_usb_audio ?
[17:55] its the kernel module(driver) for your usb sound card
[17:55] I only have one instance for mine
[17:56] Funky. I have other USB audio interfaces that work as intended, if that helps
[17:56] I'm way to tired to poke through the code and see what that error means...
[17:56] not surprised
[17:57] are you a c coder per chance?
[17:59] I am not, though I could possibly read some C.
[18:00] FAIL device='plughw:RMX90DVS,0' rate='48000' format='S32_LE' aplay: set_params:1297: Unable to install hw params:
[18:00] you should see that string at line 1297 of aplay.c
[18:01] maybe debianuser will come by tonight and debug further
[18:01] Thanks for your help wabbits, I really appreciate it
[18:02] I'll likely idle about here and look at aplay.c a bit
[18:02] And email the alsa mailing list later
[18:02] all good ideas
[18:02] best of luck
[18:02] One last thing, what's the licence on this script of yours? Can I keep it/share it?
[18:02] no licence so share away
[18:03] Thanks
[18:03] np

The issue contains an ALSA/PulseAudio troubleshooting transcript and points to aplay.c around line 1297, with failure details for plughw:RMX90DVS,0 at 48000 Hz and S32_LE. Start by clarifying the expected compatibility behavior and obtaining a reproducible test case; the issue does not define what a completed fix would look like.
