thanks for Audacity. It is great.
However I bought a new USB mic (Apogee Mic Plus) to connect to my desktop (running Ubuntu 18.04.3 on SSD and Audacity 2.3.2).
I cannot get it to work correctly. In Ubuntu->Sound I can see and hear my mic.
In Audacity I can select the mic (/dev/dsp), but when trying to record, it tells me “error -9997 Invalid sample rate”.
When I run Audacity->Help->Diagnostics->Audio device info, I get multiple SALSA devices (which I used up till now) and my one OSS device (Mic with headphone connection):
I think the problem is that no sample rates are supported. Can I change this / add sample rates? If so, where and how?
If not, is there a work-around or do I have to switch to Windows?
Audacity retrieves the list of sample rates from the device drivers. If no sample rates are listed, then that does not necessarily mean that no sample rates are supported, it just means that the device driver does not say what sample rates are supported.
I thought I do an uninstall/ install and noticed there are 2 versions of Audacity in my Software Centre. Both with different outcomes:
First I uninstalled my version, then installed:
A) version 2.3.2 (Developer: Daniel Llewellyn)
Size: 82Mb
Source: Snap Store
When I installed this, all my devices were gone except the defaults. Only one ALSA, no OSS.
Of course, I uninstalled this one and installed:
B) version: 2.3.3-0build1~ubuntu18.04 (26/11/2019)
Size 4.2 Mb
Source: lp_ppa_ubuntuhandbook1_audacity-bionic-main
Return of all my 14 devices incl OSS. However, no supported sample rates…
A quick install of 2.3.3 on a Windows 10 laptop resulted in a flawless recording & playback.
I can use the laptop for now, but I really like Ubuntu better…
You need to uninstall your current version of Audacity, then disable or remove the PPA from your sources. Audacity 2.2.1 will then be available from the main Ubuntu repository.
Try changing the default sample rate in “Edit menu > Preferences > Quality”, then restart Audacity and try a test recording in a new, empty project.
Try sample rates of:
44100
48000
96000
I don’t know if this will help, but it’s worth trying.
No, that doesn(t work either. I already tried it, and tried it again after the last install.
I noticed the LED on the mic was flashing when starting Audacity, to end in the “no operation” state (LED is blue).
When the mic can be used, the LED will stay on (green).
That’s interesting. It appears that the mic has built-in software (“firmware”) rather than just being a microphone with a class compliant USB audio chip.
I don’t see that in the Ubuntu repository. What does that say in “Help > About”?
