[21:43] <alsainput> Hello! I am trying to record using an usb to guitar cable but it volume is way too high it instantly clips
[21:44] <alsainput> I tried to lower the input using alsamixer but it says that it's already at 0db
[21:55] <alsainput> I'm trying to record on Ardour if that's of any help.
[22:35] <tomreyn> usb to guitar cable? iassume there'd have to be some chipset on the usb connector to make that possible.
[22:35] <tomreyn> is it some special cable then?
[22:37] <alsainput> Yes, there's a small chip I believe
[22:37] <alsainput> But no volume controls or anything of the sort
[22:37] <alsainput> I have always recorded with it without problems until now.
[22:38] <tomreyn> so what else changed between "always recorded with it without problems" and "now"?
[22:39] <alsainput> Honestly, just time, I have not recorded in about a month, I haven't really made any changes.
[22:39] <tomreyn> software updates? different operating system? different operating system version? different computer?
[22:39] <alsainput> Maybe the updates Ubuntu Studio gets, but other than that, nothing.
[22:40] <tomreyn> and the guitar was the same, too?
[22:40] <tomreyn> did you double check both connectors?
[22:40] <tomreyn> tried a different usb port
[22:42] <alsainput> Yes, same guitar. I noticed while checking the sound settings that when I turn up the volume (?) input: microphone - USB PnP the actual level doesn't change and lowering it to nothing doesn't change either, it basically goes from on to off.
[22:42] <Eickmeyer[m]> OvenWerks: ^^^^
[22:42] <alsainput> I'll check that right now
[22:42] <Eickmeyer[m]> If it's instantly clipping, that screams hardware problem.
[22:45] <alsainput> Yeah, just checked that and all it's good, same on the all the usb ports
[22:49] <tomreyn> alsainput: what's 'all good'? are you saying you replugged the usb and it's working now?
[22:51] <alsainput> Sorry. I tried all three usb ports and the problem is still there on all three ports. I tried with a guitar, bass and electric violin and the same problem. I tried the instruments with a regular amp to see if they could be the problem but it was all good.
[22:57] <tomreyn> the bug report has just quit
[23:14] <alsainput> Sorry, got disconnected.
[23:17] <alsainput> Is there anyway I can regulate the input levels from that device?
[23:19] <OvenWerks> Input: microphone?
[23:20] <alsainput> No, the usb input
[23:23] <alsainput> I've also noticed another problem, jack only picks up audio from the built-in microphone. It doesn't pick up any sound if I connect an external microphone
[23:24] <OvenWerks> so alsamixer -> F6 -> change device to usb device -> F4 what is the cature level?
[23:24] <OvenWerks> how are you starting jack? jack is on it's own a one audio device application)
[23:25] <alsainput> Capture is 0 and still picking up sound
[23:25] <alsainput> I start jack through qjacktl
[23:25] <alsainput> qjackctl*
[23:25] <OvenWerks> qjackctl will only allow one device at a time.
[23:26] <OvenWerks> that is normal
[23:26] <alsainput> Okay, yes but I'm just plugging a microphone on audio input (non usb) of my laptop, shouldn't that work?
[23:27] <OvenWerks> for profesional audio, all audio devices need to be forced to be the same clock.
[23:28] <alsainput> I honestly don't understand.
[23:28] <OvenWerks> if you have tried to set qjackctl to use different devices for in and out... then the internal input will no longer work.
[23:29] <OvenWerks> in a terminal this is all on one line:
[23:29] <OvenWerks> cd /tmp && wget https://community.ardour.org/files/adevices.sh && bash ./adevices.sh |pastebinit
[23:29] <Eickmeyer[m]> This is why Ubuntu Studio Controls exists.
[23:29] <Eickmeyer[m]> !ubuntustudio-controls
[23:29] <ubottu> Ubuntu Studio Controls is the application through which audio is configured in Ubuntu Studio. It configures Jack, sets the CPU governor, and ensures the user has realtime audio permissions. For more info, see !jack and https://help.ubuntu.com/community/UbuntuStudio/UbuntuStudioControls
[23:29] <OvenWerks> it will give a url paste that url here
[23:30] <alsainput> But it is working. I have system -> capture_1 and capture_2 (this are the internal mic). I also have alsa_in -> capture_1. They both work if I connect the to system -
[23:30] <alsainput> system -> playback*
[23:31] <OvenWerks> Ok so you can put a mic in and connect system capture to system:playback and can then hear the mic in output?
[23:31] <alsainput> https://paste.ubuntu.com/p/FM68HR5RKH/
[23:32] <OvenWerks> ahh, you are trying to use alsa_in
[23:32] <OvenWerks> That should be able to work.
[23:33] <alsainput> Let me explain better.
[23:35] <OvenWerks> That setup looks reasonable.
[23:35] <alsainput> I can use alsa_in capture_1 and get output. I can connect system capture_1 and get ouput. I can connect both alsa_in and system and get output from both of them at the same time. Problem is if I plug in a microphone in the microphone 3.5mm input of my laptop it won't work, the built in microphone of the laptop will still be working instead of being
[23:35] <alsainput> "overriden" by the plugged in mic.
[23:36] <OvenWerks> OK
[23:36] <OvenWerks> That sounds like a mixer problem.
[23:37] <OvenWerks> in alsamixer F6 to HDA/PCH
[23:37] <OvenWerks> F4
[23:37] <alsainput> (And I don't use Ubuntu Studio Controls because I usually have this buzzing feedback sound that is very low in volume, but when I use Ubuntu Control the constant buzzing sound turns into a beeping like sound that is heard in recordings)
[23:38] <OvenWerks> I have a level for both front mic and rear mic
[23:38] <OvenWerks> (no worries about using qjackctl and alsa_in
[23:38] <alsainput> I have for  mic boos capture and internal mic boost
[23:38] <OvenWerks> it sounds like that is not a problem and working correctly
[23:39] <OvenWerks> do you have an Input source switch?
[23:40] <alsainput> No, I don't
[23:40] <OvenWerks> Do any of the controls for capture have a ------- at the bottom of the level control?
[23:41] <OvenWerks> Maybe a screen shot of the window alsamixer is in would help.
[23:41] <alsainput> Yes, I'll upload one
[23:43] <alsainput> https://imgur.com/a/WGUpDVK
[23:48] <OvenWerks> So only the one capture, no switches. hit F3. Sometimes alsa has extra capture controls in with playback
[23:49] <alsainput> Whole list: master, headphones, speaker, pcm, mic, mic boost, s/PDIF, beep, automute, loopback and mute-led
[23:50] <alsainput> Just added the image https://imgur.com/a/WGUpDVK
[23:51] <OvenWerks> That looks like the same one as before
[23:51] <alsainput> Below is the new image
[23:51] <alsainput> https://imgur.com/Si6bcZT
[23:51] <alsainput> Sorry, sent the same link.
[23:52] <OvenWerks> Ok, nothing in alsa
[23:52] <OvenWerks> That I can tell
[23:53] <OvenWerks> if jack is not running, does a plugged in mic show up in pavucontrol?
[23:54] <alsainput> Let me close everything
[23:54] <OvenWerks> sorry
[23:54] <alsainput> It's okay haha
[23:56] <alsainput> Give me one moment
[23:57] <n4dir> OvenWerks: btw, your explanation and solution works like a charme. Pretty happy.
[23:57] <n4dir> i also switched to ubuntustudio-controls as adviced, and as of now that works very well too. including carla-patchbay (?)
[23:58] <OvenWerks> n4dir: sounds good.
[23:58] <n4dir> glad i asked.
