Re: Alsa sound errors
2013/6/6 Marc Shapiro marcns...@gmail.com So, do I create the file and add the line: ipc_gid_audio or ipc_gid_audio TRUE or something else? I guess you are running pulseaudio so you can fix your error at global level or per user level. Per user level: - copy /usr/share/alsa/alsa.conf.d/99-pulseaudio-default.conf.example in each user dir - rename it to .asoundrc - add this line 'ipc_key_add_uid yes' after the lines 'type pulse' - change ownership according to the user home dir you are working with. - log out and log back again should be enough... but if not, restart pulseaudio alsa-utils, reboot as last choice It should work. BEWARE I do not use pulseaudio at all, I use alsa and jackd instead with this setup. References: http://www.alsa-project.org/main/index.php/Asoundrc Regards /raffaele
Re: Alsa sound errors
2013/6/5 Marc Shapiro marcns...@gmail.com There are three people with logins to my desktop box -- myself, my wife and my daughter. My daughter plays Flash games with sound all the time and has no problems. I run YouTube videos and otherwise use sound with no problems. My wife gets no sound whatsoever. We used to have a problem with the sound being grabbed by something and then I would need to kill things manually, but I eliminated all KDE apps and that problem went away. I think that was back when I was still running Etch, anyway. When I need to verify that sound is working and not locked up, I just use 'play' with a .wav file. My wife was just playing a video and getting no sound, so, under my login I ran: play /home/marc/public_html/**footpain/media/montoya.wav /home/marc/public_html/**footpain/media/montoya.wav: File Size: 14.8k Bit Rate: 13.1k Encoding: GSM Channels: 1 @ 16-bit Samplerate: 8000Hz Replaygain: off Duration: 00:00:09.04 In:100% 00:00:09.04 [00:00:00.00] Out:434k [ | ] Clip:0 Done. and, as you can see, it worked just fine. So I swiched over to my wife's login and did the same thing: play /home/marc/public_html/**footpain/media/montoya.wav ALSA lib pcm_dmix.c:985:(snd_pcm_dmix_**open) unable to create IPC semaphore play FAIL formats: can't open output file `default': snd_pcm_open error: Permission denied As you can see, it failed. Can anyone tell me just what is failing and how to correct it. My first thought was that it was a permissions problem and perhaps she needed to be added to the 'audio' group, or some such, as she is only in her own group. But then I checked my daughter's account. She is also only in her own group; not in 'audio' or anything else. So that ruled out that solution. The error says 'Permission denied however, so it is some kind of permissions problem, I just don't know what. Any help will be greatly appreciated. Marc You should use ipc_key_add_uid TRUE in your .asoundrc when defining dmix. Details are in http://www.alsa-project.org/alsa-doc/alsa-lib/pcm_plugins.html Regards /r

It's not a user level permission problem, he should use ipc_key in .asoundrc if the soundcard is shared. Indeed I bet that if he reboot the system and login with his wife login everything will work just fine, problem arises when he switches from another account, no matter which user he logs in. [quote] ipc_key specfies the unique IPC key in integer. This number must be unique for each different dmix definition, since the shared memory is created with this key number. Whenipc_key_add_uid is set true, the uid value is added to the value set in ipc_key. This will avoid the confliction of the same IPC key with different users concurrently. [/quote]
