Problem accessing the mic with 2.1.1 with Azalia sound card

[tgf]

I first checked with "ps -eaf | grep pulse" that pulseaudio was running

Code: Select all

gfreeman  1842     1  0 Mar24 ?        00:02:28 /usr/bin/pulseaudio --start --log-target=syslog

I then ran pavucontrol and connected the sound source to the Mic port, confirming that pavucontrol could see the signal.
With pavucontrol on Recording, I issued the command "arecord -d 4 /tmp/test.wav". Pavucontrol window changed from

Code: Select all

No application is currently recording audio

to

Code: Select all

ALSA plugin [aplay]: ALSA Capture from [Built-in Audio Analog Stereo]

and below the arecord command was the message

Code: Select all

Recording WAVE '/tmp/test.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono

[steve]

Code: Select all

Recording WAVE '/tmp/test.wav' : Unsigned 8 bit, Rate 8000 Hz, Mono

That could be the problem.
I'm not certain, but I think that Audacity expects / requires the audio sample format to be at least 16 bit.

This article gives a general idea of how to change the default format for PulseAudio: http://www.overclock.net/a/how-to-get-t ... pulseaudio

I'd suggest that you try setting the default format to signed 16-bit, and a sample rate of 44100 Hz.

This is what I have:

Code: Select all

default-sample-format = s16le
default-sample-rate = 44100
alternate-sample-rate = 48000
default-sample-channels = 2
default-channel-map = front-left,front-right

You will need to at least restart Pulse - I'd suggest logging out and back in again, or rebooting to ensure that the changes take effect.

(Leave Audacity preferences at the default "32-bit float" 44100 Hz.)

BE SURE TO MAKE THE BACKUP.

If the above does not work, there is a much more in-depth article on the subject here: https://wiki.archlinux.org/index.php/Pu ... figuration

I don't think that is the problem. "arecord" has 8000 Hz and unsigned 8 bit as the defaults. I can change them with

Code: Select all

arecord -d 4 -r 192 -f cd /tmp/test.wav

I did look at /etc/pulse/daemon.conf as you suggested. It indicated that

Code: Select all

 default-sample-format = s16le
 default-sample-rate = 44100
 alternate-sample-rate = 48000
 default-sample-channels = 2
 default-channel-map = front-left,front-right

were the defaults. I uncommented those lines and re-logged in, but it has made no difference.
Now, I am seeing "default" as the only selectable input.

I'm running out of ideas.
Look in "Help > About Audacity > Build Information". Which version of PortAudio and wxWidgets has Audacity been built with?

[Gale Andrews]

Perhaps tgf should build current Audacity from source code http://www.audacityteam.org/download/source/. We recently updated PortAudio which has a lot of fixes for Linux.

[Gale Andrews]

Are you using system wxWidgets? Audacity will fail to compile with the issues you see in that case, because system wxWidgets on OpenSUSE uses STL.

If you self-build wxWidgets with no configure arguments I would assume Audacity will build against it.

I have run "./configure" and then "make" but compilation is failing because of data type issues:

I think this may be fixed in jengelh's fork:
https://github.com/jengelh/audacity

Unfortunately the pull request from jengelh has merge conflicts with the current audacity/audacity code, but if you can confirm that jengelh's fix works, then that may help to get the fix committed.

ThomasFeher has already confirmed that commit fixes building on OpenSUSE https://github.com/audacity/audacity/pull/112 but Paul did not want to commit it even if he resolved the conflicts.

If no-one reviews and commits we'll have to track it on Audacity Bugzilla.
