Re: [Discuss-gnuradio] Error Running Examples

[Prateek Dayal]

No .. the command shows no error ....

but do I need the OSS driver ... I am having alsa and I can play mp3
files and other stuff ...

is it that the audio.sink requires OSS specifically ...

in that case should install the  gr-audio-oss 

Regards,

Prateek
