[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] <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.
