No sound output with audacity
Last modified: 2007-11-30 17:12:23 EST
Description of problem: A freshly upgraded (fc6 -> f7) machine has a version of audacity (1.3.2-beta unicode) which fails to output any sound no matter which playback device is selected. Starting with the default playback device "OSS: /dev/dsp1" produces the following errors: [ush@larry temp]$ audacity ContinuumMedicumRomanum.wav JACK tmpdir identified as [/dev/shm] Expression '*idev = open( idevName, flags )' failed in 'src/hostapi/oss/pa_unix_oss.c', line: 807 Expression 'OpenDevices( idevName, odevName, &idev, &odev )' failed in 'src/hostapi/oss/pa_unix_oss.c', line: 861 Expression 'PaOssStream_Initialize( stream, inputParameters, outputParameters, streamCallback, userData, streamFlags, ossHostApi )' failed in 'src/hostapi/oss/pa_unix_oss.c', line: 1226 Attempting to select a different output device (Edit>Preferences>AudioI/O>ALSA:Intel82801DB-ICH4) produces the following shorter message and eliminates all the apparent portaudio related errors above: [ush@larry temp]$ audacity ContinuumMedicumRomanum.wav JACK tmpdir identified as [/dev/shm] Version-Release number of selected component (if applicable): audacity-1.3.2-14.fc7 portaudio-18.1-8.fc6 How reproducible: I tried it three times with three different files. Steps to Reproduce: 1. open any .wav with audacity 2. edit>preferences>audio-i/o observe that OSS is set as default 3. try to play a file and hear nothing, switch to alsa and check settings with "alsactl", try to play file again, hear nothing. Actual results: No audible output. Can see audacity behaving in every other way as though it's playing a file including internal volume meter bouncing up and down. Expected results: ALSA selected by default. JACK shouldn't ever be mentioned on Fedora 7. OSS shouldn't be used either. Sound should be heard. Additional info: This was an upgraded system, but going through the .audacity and .audacity-data files in ~ I couldn't see anything that should have been causing either OSS or Jackd to be selected.
> portaudio-18.1-8.fc6 That one is not used at all. Audacity builds with an included PortAudio v19 library. > JACK shouldn't ever be mentioned on Fedora 7 Audacity is built with optional support for JACK, as JACK is included with Fedora. The tmpdir is printed as part of querying PortAudio for the available audio interfaces. > OSS shouldn't be used either. But of course it should be built in as an option to choose from. Certainly until Audacity's ALSA support will be much more stable and will work without problems for many more people. The last stable release of Audacity, 1.2.6, was OSS-only by default and included only incomplete and broken ALSA drivers. [...] Anyway, please report this upstream to the Audacity developers. Thank you. There have been heavy changes in PortAudio in Audacity 1.3.3-beta already and even more breakage in cvs (1.3.4-beta). Not an option for a rather safe upgrade yet.
