A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1228> ====================================================================== Reported By: hil Assigned To: ====================================================================== Project: ALSA - liboss Issue ID: 1228 Category: Reproducibility: always Severity: minor Priority: normal Status: new ====================================================================== Date Submitted: 07-03-2005 09:09 CEST Last Modified: 07-12-2006 17:52 CEST ====================================================================== Summary: Skype Does not work with aoss Description: I downloaded alsa-oss-1.0.9rc2 and install by # ./configure --with-aoss=yes && make && make install as root. Virtually every program works except skype (http://www.skype.com/) version 1.1.0.13_API. I downloaded the Fedora version of skype from the skype official website. Skype only uses /dev/dsp. I guess skype uses /dev/dsp as microphone input as well. I could not hear anything and the microphone did not work as well if I run skype like aoss /usr/bin/skype. If I run skype without aoss, then skype works just fine. ====================================================================== Relationships ID Summary ---------------------------------------------------------------------- related to 0001224 artsd-like style ====================================================================== ---------------------------------------------------------------------- Raymond - 06-09-06 03:28 ---------------------------------------------------------------------- It depend on aoss open which pcm device and the sound card 1) hw 2) plughw 3) default 4) ALSA_OSS_PCM_DEVICE The "type plug" allow mono/stereo conversion, but it also changed the values return by snd_pcm_hw_params_get_xxx_min() and snd_pcm_hw_params_get_xxx_max() #include <alsa/asoundlib.h> #include <stdio.h> char *device_name[3]={"hw:0","plughw:0","default"}; int main(int argc, char **argv) { snd_pcm_t *pcm; snd_pcm_info_t *pcm_info; snd_pcm_hw_params_t *hw_params; snd_pcm_format_t format; char device[16]; int err,i; int dir,sub; int channels,chn_min,chn_max; printf("ALSA %s\n",snd_asoundlib_version()); for (i=0; i<3; i++) { strcpy(device,device_name[i]); for (dir=SND_PCM_STREAM_PLAYBACK; dir<= SND_PCM_STREAM_CAPTURE; dir++) { err = snd_pcm_open(&pcm, device, dir,SND_PCM_NONBLOCK); if ( err < 0 ) { printf(" open %s fail : %s\n",device,snd_strerror(err)); } else { snd_pcm_info_alloca(&pcm_info); err = snd_pcm_info(pcm, pcm_info); if ( err < 0 ) { printf(" pcm_info : %s\n",snd_strerror(err)); }; printf("%s %s %s\n",device,snd_pcm_info_get_name(pcm_info),dir == SND_PCM_STREAM_PLAYBACK ?
