Following the kfusd patch, here is a small patch to make oss2jack work fine against jack2. It works against jack1 already because jack1's version of jack_set_samplerate_callback() actually executes the callback function, while jack2 does not do it right away. So I followed Stephane Letz's advice and call jack_get_sample_rate() in oss2jack in jack_init() instead. Please be aware that you may get a reject by applying due to screwed spacing. I had some funny issues with this lately (and I use emacs for source code ... weird). ------ PATCH start ------------------ --- oss2jack-0.25.orig/src/oss2jack/oss2jack.c 2009-05-18 19:57:17.757704457 +0200 +++ oss2jack-0.25/src/oss2jack/oss2jack.c 2009-05-18 20:05:04.397724051 +0200 @@ -633,7 +633,7 @@ jack_set_error_function(jack_error); - info->client = jack_client_new("oss-dsp"); + info->client = jack_client_open("oss-dsp", JackNullOption, NULL); if(info->client == NULL) { @@ -652,6 +652,9 @@ jack_set_sample_rate_callback(info->client, jack_srate, info); jack_set_buffer_size_callback(info->client, jack_buffer_size, info); + /* initialize current sample rate for jack2 at startup */ + (void)jack_srate(jack_get_sample_rate(info->client), info); + jack_on_shutdown(info->client, jack_shutdown, info); info->last_frame_size = 64; ------- PATCH end ------------------------------ Cheers!
