Abort when running scream server

[ryant00000]

When running scream with either pulse or alsa, application appears to work until audio output hits the application, when it aborts.

Pulse - Application registers with pulse and volume can be controlled until it crashes scream -o pulse -v Using Pulseaudio output Starting multicast receiver Invalid channel mapping, falling back to CHANNEL_MAP_WAVEEX. Assertion 'pa_channels_valid(channels)' failed at ../pulseaudio/src/pulse/channelmap.c:401, function pa_channel_map_init_extend(). Aborting. Aborted (core dumped)

Alsa - scream -o alsa -v Using ALSA output Starting multicast receiver ALSA lib pcm.c:8627:(snd_pcm_set_params) Channels count (0) not available for PLAYBACK: Invalid argument snd_pcm_set_params: Invalid argument Segmentation fault (core dumped)

Sorry for the late answer. This looks like you are running an old Scream driver version against a newer Receiver. Please make sure both the driver and the receiver are current.

Hi, I'm also getting this same problem, but only after it runs a bit, so it might be a different bug. I'm using 3.5 to receive on Linux, and 3.6 to send on Windows, but considering the release notes I assume these are the same "version"?
