Hey Group;
I have the record player > phono In > line out going to the sound card Line In. Hopefully the impedance is good enough and the level is OK. It plays out of the speakers and sounds OK also. Now for the question ? I would like to save the music as a mp3, ogg or whatever. Kmix spots it as a Line Input. What is needed to capture it and put it in a file. Say like a mixer record output
No luck with audacity? The Input selections in 1.3.2 are Vol, Line, Mic, CD, Line1, Phonein, Phoneout and Video. You should then be able to record from the Line input.
File --> Export as --> MP3 or whatever format. Regards Sid. The problem is Sid; That Audacity will only work as a user if you change the permissions on /dev/dsp. I tried several and only 777 seem to work. However, Audacity will only "Record" once and then it fails on the second try. Now this may be a "Me" problem understanding the way it saves data. I have fixed it by removing /home/donn/.audacity-data and trying it again. It ask for lang. which I set and then it comes up with full features.
I and several others have had similar permissions problems with gizmo which actually said there was no audio device. I did strace and submitted it to the forum, but the mystery continued. Then I had a brainwave, tried it as root and it was AOK. So I added the user to audio in /etc/group, also did the same for video a while back when kaffeine complained about no video, though OK with audio. was audio:x:17: now audio:x:17:lancelot video:x:33:lancelot It's a strange behaviour, stuff used to come up with ownerships in /dev of e.g <user>:audio, then quite a while ago on Mandriva and more recently on openSUSE, they are "root:audio", so the user can't get to them. Don't know whether it's a bug or feature, but it's a gotcha. Most apps work, but there is always one or two that experience the problem. It's only last week I got this problem when I fired up gizmo the first time in months. Without the changes my DVB card would complain when kaffeine is fired up. # l -R /dev/dvb /dev/dvb: total 0 drwxr-xr-x 3 root root 60 2007-03-10 07:27 ./ drwxr-xr-x 13 root root 16520 2007-03-12 00:19 ../ drwxr-xr-x 2 root root 120 2007-03-10 07:27 adapter0/ /dev/dvb/adapter0: total 0 drwxr-xr-x 2 root root 120 2007-03-10 07:27 ./ drwxr-xr-x 3 root root 60 2007-03-10 07:27 ../ crw-rw----+ 1 root video 212, 4 2007-03-10 07:27 demux0 crw-rw----+ 1 root video 212, 5 2007-03-10 07:27 dvr0 crw-rw----+ 1 root video 212, 3 2007-03-10 07:27 frontend0 crw-rw----+ 1 root video 212, 7 2007-03-10 07:27 net0 Regards Sid. -- Sid Boyce ...

Sound and DVB devices are supposed to be detected by hal. hal-resmgr will take care of device permissions when you log in then. There is no need to put users in the audio or video group. If permission handling doesn't work for some reason please file a bug report, assign it to me and attach the output of "lshal", "/usr/sbin/hal-resmgr --list-all" and "/sbin/resmgr sessions". cu Ludwig -- (o_ Ludwig Nussel //\ SUSE Labs V_/_ http://www.suse.de/ SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg) --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-factory+help@opensuse.org

It didn't work before, now I've just removed the user from /etc/group and gizmo doesn't complain. I shall try it later after a reboot. # /usr/sbin/hal-resmgr --list-all UDI /org/freedesktop/Hal/devices/usb_device_68e_f2_noserial_usbraw Device /dev/bus/usb/003/017 Class scanner UDI /org/freedesktop/Hal/devices/usb_device_46d_928_noserial_video4linux Device /dev/video0 Class v4l UDI /org/freedesktop/Hal/devices/pci_10de_8a_oss_pcm_0_0 Device /dev/audio Class sound UDI /org/freedesktop/Hal/devices/pci_10de_8a_oss_pcm_0 Device /dev/dsp Class sound UDI /org/freedesktop/Hal/devices/pci_10de_8a_oss_pcm_1 Device /dev/adsp Class sound UDI /org/freedesktop/Hal/devices/pci_10de_8a_oss_mixer__1 Device /dev/mixer Class sound UDI /org/freedesktop/Hal/devices/computer_alsa_sequencer Device /dev/snd/seq Class sound UDI /org/freedesktop/Hal/devices/storage_model_LITE_ON_DVDRW_SOHW_1673S Device /dev/hdc Class cdrom UDI /org/freedesktop/Hal/devices/usb_device_4b8_103_noserial_usbraw Device /dev/bus/usb/003/010 Class scanner UDI /org/freedesktop/Hal/devices/pnp_PNP0501_serial_platform_0 Device /dev/ttyS0 Class modem UDI /org/freedesktop/Hal/devices/computer_alsa_timer Device /dev/snd/timer Class sound UDI /org/freedesktop/Hal/devices/pci_10de_8a_alsa_playback_2 Device /dev/snd/pcmC0D2p Class sound UDI /org/freedesktop/Hal/devices/pci_10de_8a_alsa_capture_1 Device /dev/snd/pcmC0D1c Class sound UDI /org/freedesktop/Hal/devices/pci_10de_8a_alsa_playback_0 Device /dev/snd/pcmC0D0p Class sound UDI /org/freedesktop/Hal/devices/pci_10de_8a_alsa_capture_0 Device /dev/snd/pcmC0D0c Class sound UDI /org/freedesktop/Hal/devices/pci_10de_8a_alsa_control__1 Device /dev/snd/controlC0 Class sound UDI /org/freedesktop/Hal/devices/pci_14f1_8802_dvb_2 Device /dev/dvb/adapter0/net0 Class dvb UDI /org/freedesktop/Hal/devices/pci_14f1_8802_dvb_1 Device /dev/dvb/adapter0/frontend0 Class dvb UDI /org/freedesktop/Hal/devices/pci_14f1_8802_dvb_0 Device /dev/dvb/adapter0/dvr0 Class dvb UDI /org/freedesktop/Hal/devices/pci_14f1_8802_dvb Device /dev/dvb/adapter0/demux0 Class dvb # /sbin/resmgr sessions :0 lancelot /dev/tty1 root Regards Sid. -- Sid Boyce ...
