Description of problem: - The cw program within the unixcw does not generate morse code from stdin or from a file. It does work from the keyboard. Version-Release number of selected component (if applicable): - unixcw-3.5.1-1.fc30.x86_64 How reproducible: Always. Also fails in Fedora 29. Steps to Reproduce: A. Entering characters from the keyboard WORKS. 1. # dnf install unixcw 2. $ cw 3. Type: hello (ENTER) 4. You hear the generated morse code with the default settings. Press Ctrl-C or Ctrl-D to exit. B. Piping into cw FAILS. 1. $ echo hello | cw 2. The word "hello" is echoed to the console, but you only hear a single beep. C. Generating morse code from a text file also FAILS. 1. $ echo hello > data.txt 2. $ cw -f data.txt 3. The word "hello" is echoed to the console, but you only hear a single beep. (Same result as in test B above). 4. $ cw --infile=data.txt 5. The word "hello" is echoed to the console, but you only hear a single beep. (Same result as in test B above). Actual results: liveuser@localhost-live ~]$ echo hello | cw cw: PulseAudio output not available (device: ( default )) cw: OSS output not available (device: /dev/audio) hello --> hello in morse code is not heard. Single beep only. [liveuser@localhost-live ~]$ Expected results: You should hear the generated morse code, just as you do if you type in the text directly from the keyboard (test A above). Additional info: Works in Ubuntu 18.04.
Testing on Fedora 29 - Recompiling unixcw from source after installing pulseaudio-libs-devel-12.2-1.fc29.x86_64 package seems to have resolved the problem. $ rpmbuild --rebuild ~/unixcw-3.5.1-1.fc30.src.rpm [..] configure: ---------------------------------------------- configure: ------ unixcw 3.5.1 build configuration ------ configure: operating system: ...................... linux-gnu configure: build libcw: ........................... yes configure: libcw soname version: ..............

Thanks!
Hopefully a simple rebuild fixes the problem but it doesn't make any sense... Looking at the build logs for the f29 build, pulseaudio support is enabled and checking root.log, pulseaudio-libs-devel is installed and it's the same version/release you reference.
WORKAROUND: After further testing with the F30 live distribution, I've found that the "cw" program is somehow dependent on the pulseaudio-libs-devel package being installed on the *run-time* host (not just the host that the unixcw RPM was built on). Demonstration: 1. Boot the F30 live distribution, open a terminal, "su -" to become root. 2. Install unixcw # dnf install -y unixcw 3. Open a normal non-root window to test. FAILS. $ echo hi | cw 4. From the root terminal, install the pre-requisite RPMs for pulseaudio-libs-devel # dnf install -y glib2-devel libblkid-devel libffi-devel libmount-devel libselinux-devel libsepol-devel libuuid-devel pcre2 pcre2-devel pcre2-utf16 pcre2-utf32 pcre pcre-cpp pcre-devel pcre-utf16 pcre-utf32 zlib-devel 5. Retest in the non-root window to test. STILL FAILS. $ echo hi | cw 6. Now install pulseaudio-libs-devel in the root terminal. No other dependent RPMs are needed: [root@localhost ~]# dnf install pulseaudio-libs-devel Last metadata expiration check: 0:09:47 ago on Thu 02 May 2019 12:55:13 PM EDT.

Was working on Fedora 30 as described above with the pulseaudio-libs-devel rpm installed. After a Fedora 30->31 upgrade ( https://fedoramagazine.org/upgrading-fedora-30-to-fedora-31/ ), the "cw" program now does not generate *any* sound on Fedora 31. BROKEN. # rpm -qi unixcw Name : unixcw Version : 3.5.1 Release : 2.fc31 Architecture: x86_64 [..] $ echo hello |cw cw: PulseAudio output not available (device: ( default )) cw: OSS output not available (device: /dev/audio) ALSA lib pulse.c:242:(pulse_connect) PulseAudio: Unable to connect: Connection refused cw: ALSA output not available (device: default) hello $
Ok, I figured out part of the problem. The method used to dlopen pulse is wrong, it depends explicitly on libpulse-simple.so (not the SOVERSION named library) which is only provided by the devel package. Working on it but I'm not much of a C/C++ guy.

Interesting, I'm still on F30 and it will play one letter for me then stop.
The version from testing works for me on my freshly upgraded Fedora 31 box.
