    When I try to build the module separately, In the CMakeCache it shows following.

    //The ALSA (asound) include directory
    ALSA_INCLUDE_DIR:PATH=/usr/include
    
    //The ALSA (asound) library
    ALSA_LIBRARY:FILEPATH=/usr/lib/x86_64-linux-gnu/libasound.so

      I'm trying to build Qt 6.5 with Qtmultimedia module and I'm having issue with enabling ALSA backend. I've installed libasound2, libasound2-dev, libasound2-data, gstreamer1.0-alsa, libgstreamer1.0-dev packages. I was able get PulseAudio enabled. I need Qt ALSA support for application I'm working on. Any help is really appreciated. I'm following this guide.

      Thanks in advance.

      @Imeshsps Check the config.log file - you should find more detailed information why ALSA was disabled.

        @jsulm said in Qt6.5 Qtmultimedia ALSA Issue:

        config.log

        Hey @jsulm ,
        Thank you for your response. Can I know, is it possible to get both ALSA and PulseAudio available at same time ? or only one can be available ?

        Also, I found config.summary, where can i find config.log?

        Here it mentions,

        With Qt 6.4, you can test the FFmpeg backend right now by using a Qt build that has FFmpeg enabled and >setting the QT_MEDIA_BACKEND environment variable to ffmpeg:
        
        export QT_MEDIA_BACKEND=ffmpeg"
        

        Should we do something similar to enable ALSA here? I tried setting QT_MEDIA_BACKEND="alsa" but no luck.

          Inside the build folder (simply use find command inside build folder: find . -name config.log).

            That's the first thing I did but I was not able to find it. No results for *.log either.

                  @Imeshsps Are any modules still missing? Or do you get any other errors in the log?

                    @jsulm Hey, I tried running configure of qt 5.15.9 for host PC and ALSA was enabled on that. In same PC, i'm still not being able to enable ALSA for host PC. currently i'm trying on qt-everywhere-src-6.5.0.

                    following is the configuration summery when i try to complie only the Qtmultimedia module.

                      @jsulm Hey, I tried running configure of qt 5.15.9 for host PC and ALSA was enabled on that. In same PC, i'm still not being able to enable ALSA for host PC. currently i'm trying on qt-everywhere-src-6.5.0.

                      following is the configuration summery when i try to complie only the Qtmultimedia module.

                      cmake -GNinja -DCMAKE_INSTALL_PREFIX=/opt/Qt6.5/6.5.0/gcc_64 /home/user/qtmultimedia/ --log-level=VERBOSE
