Hi all, I get the following when ms_init() runs. I found a reference to this error in the archive and it was resolved by editing alsa.conf (or perhaps /etc/asound.conf?) http://lists.gnu.org/archive/html/linphone-developers/2009-07/msg00064.html Unfortunately, I haven't figured out what the edits should be. Does anyone have any suggestions? Thanks Denny ============================================================= ortp-message-Registering all filters... ortp-message-Registering all soundcard handlers ortp-message-Card ALSA: default added ALSA lib conf.c:4600:(snd_config_expand) Unknown parameters 0 ALSA lib control.c:902:(snd_ctl_open_noupdate) Invalid CTL default:0 ortp-warning-Could not attach mixer to card: Invalid argument ortp-message-Card ALSA: omap3530lv_som added ortp-message-Card OSS: /dev/dsp added ortp-message-Registering all webcam handlers ortp-message-Webcam StaticImage: Static picture added ortp-message-Loading plugins ortp-message-Cannot open directory /usr/lib/mediastreamer/plugins: No such file or directory ortp-message-ms_init() done ============================================================= I have an OMAP ARM board with a TI TPS65950 (i.e. TWL4030) and we're only using a portion of the audio channels. Here's some of my ALSA config (the mixer works fine with ALSA). What other information can I provide? ========================================== # cat /proc/asound/cards 0 [omap3530lvsom ]: twl4030 - omap3530lv_som omap3530lv_som (twl4030) # aplay -L default:CARD=omap3530lvsom omap3530lv_som, Default Audio Device null Discard all samples (playback) or generate zero samples (capture) # amixer controls numid=4,iface=MIXER,name='Master Playback Switch' numid=6,iface=MIXER,name='Analog Capture Volume' numid=3,iface=MIXER,name='DAC2 Analog Playback Volume' numid=2,iface=MIXER,name='DAC2 Digital Coarse Playback Volume' numid=1,iface=MIXER,name='DAC2 Digital Fine Playback Volume' numid=5,iface=MIXER,name='TX2 Digital Capture Volume' ========================================== |
