Hello all. I am pretty new to Freeswitch and have an experimental container on Proxmox 6.3 Debian 10 to play with. The goal is to get mod_unimrcp working. To that end, I have mod_tts_commandline (installed from binary with FusionPBX as part of the default install) listed in modules.conf.xml /etc/freeswitch/autoload_configs/modules.conf.xml <!-- Speech Recognition / Text to Speech --> <load module="mod_unimrcp"/> <load module="mod_tts_commandline"/> <load module="mod_flite"/> I have tried it with and without mod_flite enabled. Mod_tts_commandline refuses to pull a sound file and the debug log seems to blame mod_sndfile. This is using the example from the mod_tts_commandline page <https://freeswitch.org/confluence/display/FREESWITCH/mod_tts_commandline#mod_tts_commandline-Configuringmod_tts_commandline> as dialplan shows following the debug log output below: 2021-02-26 15:19:24.713040 [NOTICE] mod_dptools.c:1406 Channel [sofia/internal/102@66.151.243.45] has been answered 2021-02-26 15:19:24.713040 [DEBUG] switch_channel.c:3865 (sofia/internal/ 102@66.151.243.45) Callstate Change RINGING -> ACTIVE 2021-02-26 15:19:24.713040 [DEBUG] sofia.c:7326 Channel sofia/internal/ 102@66.151.243.45 entering state [completed][200] EXECUTE [depth=0] sofia/internal/102@66.151.243.45 speak(tts_commandline|pico|This is an example of using tts_commandline) 2021-02-26 15:19:24.713040 [DEBUG] switch_ivr_play_say.c:3023 OPEN TTS tts_commandline 2021-02-26 15:19:24.713040 [DEBUG] switch_ivr_play_say.c:3033 Raw Codec Activated 2021-02-26 15:19:24.713040 [DEBUG] mod_tts_commandline.c:160 Executing: echo 'This is an example of using tts_commandline' | text2wave -f 8000 > '/tmp/0665a30d-2bb8-40fe-b5a6-9625bd58306e.tmp.wav' 2021-02-26 15:19:25.433013 [WARNING] mod_sndfile.c:281 Error Opening File [/tmp/0665a30d-2bb8-40fe-b5a6-9625bd58306e.tmp.wav] [File contains data in an unknown format.] 2021-02-26 15:19:25.433013 [ERR] mod_tts_commandline.c:170 Failed to open file: /tmp/0665a30d-2bb8-40fe-b5a6-9625bd58306e.tmp.wav 2021-02-26 15:19:25.433013 [DEBUG] switch_ivr_play_say.c:2741 Speaking text: This is an example of using tts_commandline 2021-02-26 15:19:25.433013 [DEBUG] sofia.c:7326 Channel sofia/internal/ 102@66.151.243.45 entering state [ready][200] 2021-02-26 15:19:25.433013 [DEBUG] switch_ivr_play_say.c:2905 done speaking text 2021-02-26 15:19:25.433013 [NOTICE] switch_core_state_machine.c:386 sofia/internal/102@66.151.243.45 has executed the last dialplan instruction, hanging up. 2021-02-26 15:19:25.433013 [NOTICE] switch_core_state_machine.c:388 Hangup sofia/internal/102@66.151.243.45 [CS_EXECUTE] [NORMAL_CLEARING] The dialplan for extension I am testing looks like this: <extension name="tts_commandline_test"> <condition field="destination_number" expression="^561$"> <action application="speak" data="tts_commandline|pico|This is an example of using tts_commandline"/> </condition> </extension> The code lines mentioned in debug seem to be pretty mundane, not that I really know what I am looking for:

From mod_tts_commnandline line 160: switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_DEBUG, "Executing: %s\n", message); I tried setting the /tmp directory to 777 but that didn't help and the error output was identical. mod_tts_commandline never reports an error on creation and it looks like the next part of of mod_tts_commandline would print an error if it did like this: if (switch_system(message, SWITCH_TRUE) < 0) { switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Failed to execute command: %s\n", message); ret = SWITCH_STATUS_FALSE; goto done; } if (switch_core_file_open(info->fh, info->file, 0, //number_of_channels, info->rate, //samples_per_second, SWITCH_FILE_FLAG_READ | SWITCH_FILE_DATA_SHORT, NULL) != SWITCH_STATUS_SUCCESS) { switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Failed to open file: %s\n", info->file); ret = SWITCH_STATUS_FALSE; goto done; }

Starting at line 279 in mod_sndfile (sorry for the space formatting): if (!context->handle) { if (sndfile_perform_open(context, path, mode, handle) != SWITCH_STATUS_SUCCESS) { switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_WARNING, "Error Opening File [%s] [%s]\n", path, sf_strerror(context->handle)); status = SWITCH_STATUS_GENERR; goto end; } } According to the dptools docs <https://freeswitch.org/confluence/display/FREESWITCH/mod_dptools%3A+playback#mod_dptools:playback-3.1> and libsndfile wav has been supported forever and it would seem highly unlikely that is an issue. I check the /tmp directory and no files are present but I don't know if they are being deleted by some cleanup process or just not created. Not knowing C, it seems like mod_sndfile never received a file handle but that is just a guess. Other Freeswitch apps are writing to the /tmp directory (at least there are some files in there). Maybe someone sees an error from mod_tts_commandline I don't see or knows I am doing something stupid. Any help would be appreciated. I only found 2 references to the error in the mail history and neither had anything to do with a similar issue.
