The package that comes with arch does not support pulse audio:
rdesktop-vrdp -help
'-r sound:[local[:driver[:device]]|off|remote]': enable sound redirection
remote would leave sound on server
available drivers for 'local':
oss: OSS output driver, default device: /dev/dsp or $AUDIODEV
I ended up compling rdesktop from https://github.com/rdesktop/rdesktop:
# run `autoreconf` -i first if configure is missing
./configure --with-sound
make
sudo make install
This resulted in pusle support:
'-r sound:[local[:driver[:device]]|off|remote]': enable sound redirection
remote would leave sound on server
available drivers for 'local':
pulse: PulseAudio output driver, default device: system dependent
alsa: ALSA output driver, default device: default
oss: OSS output driver, default device: /dev/dsp or $AUDIODEV
libao: libao output driver, default device: system dependent
Use:
/opt/myrdesktop/bin/rdesktop -u "user_name" -r sound:local:pulse windows_ip_addr
