Out of curiousity, does anything change if you install the FC3 alsa-lib? I fetched and tried alsa-lib-1.0.6-3.i386.rpm and alsa-lib-devel-1.0.6-3.i386.rpm as well as 1.0.6-5. 1.0.6-3 didn't make any difference at all. 1.0.6-5 allowed me to push the 'play' button once (and hear sound), but pushing play a second time, still wedged the application. If you use the OSS compat, does it work? (if Audacity has that option) The other output driver option is '/dev/oss'. Yes that works, (always did), but the latency/delay between the the screen (ie. visual display of the waveform being emitted) and the actual audio out, make that driver worthless. Only when selecting ALSA as the output driver, will the application perform acceptably. I also updated my FC3 system with the latest and greatest (from Dec 1/01 00:00), and the latest Audacity (which only supports /dev/dsp) and it works fine, and does not have that same latency problem. So, if the behavior is different on FC2 + FC3 alsa-lib and FC3 + updates... what else is different? Only the kernel? Also, potentially, audacity, since the FC3 test sucked the latest version of audacity. Unfortunately, Audacity's "about" screen must be doing some kind of unicode thing, because its text is all rendered as 'small boxes'. Using RPM -q gives us the following test matrix: --> FC2 + FC3 libraries + audacity-1.2.2-1.1.fc1.fr = fails --> FC3 + FC3 libraries + audacity-1.2.3-2.1.fc3.fr = works So my next step will be to find the RPM that apt-get auto-installed on FC3 onto the FC2 machine, and re-test the new combo. Fedora Core 2 is now maintained by the Fedora Legacy project for security updates only. If this problem is a security issue, please reopen and reassign to the Fedora Legacy product. If it is not a security issue and hasn't been resolved in the current FC3 updates or in the FC4 test release, reopen and change the version to match. Is this bug still alive? |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.3) Gecko/20040922 Description of problem: Audacity works driving audio using the ALSA driver under kernels prior to 2.6.9. (i.e. 2.6.8-1.521) However since installing newer kernels (as released from Fedora) audacity now hangs when trying to play audio. It hangs on both 2.6.9-1.3_FC2 and 2.6.9-1.6_FC2. (My ALSA device is Intel 82801-DB-ICH4) Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. Boot with kernel 2.6.9-1.3_FC2 or later. 2. Start Audacity and load a sound file. 3. Select File->Preferences->Audio IO->Playback Device = ALSA 4. Push 'play' button. Actual Results: Audacity hangs, its cursor does not move, no sound. Expected Results: no hang, moving cursor et.al., sound... Additional info:
