You posted to bug #510105 Apparently, even with alsamixer -c0 reporter cannot turn on any input channel to make tv card audio output work. That means that internal routing from audio between tv card and sound hw doesn't work/isn't enabled. tvtime can't do anything about it if no mixer channel controls the tv audio output. It's more of another tv card driver problem (also see bug 497750 - same reporter, but F10). I agreed with you. I posted this thread on the Fedora user list in order to straighten out my use of controls before returning to bugzilla. Yeah, it's not really a duplicate anymore, but not a PulseAudio bug either since switching on a silent audio channel [with tvtime] yields silence, of course. (With F11, almost every tvtime user runs into the problem that the old OSS audio system is no longer supported and that tvtime cannot use the ALSA mixers instead. Only the tvtime update changes that. The majority of users connect tv card and audio card, though, which doesn't apply to you.) And how? ANd what does your tv card driver does related to audio? I have filed a bug about PulseAudio and my tv tuner card #510105 and subsequnetly about ALSA + PulseAudio #511178. It would really be interesting to retest the tvtime+mplayer solution. Decoding an mpeg a/v stream with mplayer sounds really plausible.

That adds another level on top of ALSA. If you keep PulseAudio running, you rely on PulseAudio to get several things right, and you cannot influence it since PulseAudio adds itself as another layer on top of ALSA. Hence you see a pulse device instead of the default (hw:0) device, for example. Same for input. I then tried the pavucontrol gui configured to 'Profile: Output Analog Stereo + Input Analog Stereo'. Input Analog Stereo to me means it refers to Microphone and Line input jacks which are connected with your onboard audio chipset. Unless somebody disagress, that is the operation mode where you would need to place an audio cable between tv card and input jack. Unlike digital input. The Profile I choose, 'Output Analog Stereo + Input Analog Stereo', gave me the most detail under the Playback, Output Devices and Input Devices tabs. In fact, when using RhythmBox, Playback and Output Devices tabs showed the application name and a sound activity bar. Similarly, when playing a video on CNN, Playback showed 'ALSA plug-in [firefox]' and sound activity. However, when using tvtime no application is recognized by pavucontrol. Again, that is because tvtime doesn't do any audio playback at all. $ amixer contents numid=4,iface=MIXER,name='Master Playback Switch' ; type=BOOLEAN,access=rw--,values=1 : values=on numid=3,iface=MIXER,name='Master Playback Volume' ; type=INTEGER,access=rw--,values=2,min=0,max=65536,step=1 : values=57583,57583 numid=2,iface=MIXER,name='Capture Switch' ; type=BOOLEAN,access=rw--,values=1 : values=on numid=1,iface=MIXER,name='Capture Volume' ; type=INTEGER,access=rw--,values=2,min=0,max=65536,step=1 : values=65536,65536 This too suggests I should use 'Master' as the tvtime control/channel. Can't follow that conclusion. 'Master' controls the final volume of the sum of all active channels. It doesn't control which capture channel is active and whether its volume is levelled up at all. It also doesn't control whether any signal is sent to an input channel (in analogue mode). Now, amixer defaults to sound card 0 (hw:0), but it can show other sound cards using the -c option (-c n). No combination of amixer and -c1 produces anything useful other than the standard help list on stdout/stderr. You don't have a device '1'. Your onboard chipset is the only one, '0'. -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

To get a clean start by first getting tvtime working with ALSA alone, I removed PulseAudio, rebooted and ran: ]$ amixer controls and amixer -c 0 controls ]$ amixer scontrols and amixer -c 0 scontrols (just for to see) On both (to be expected) I got: Simple mixer control 'Master',0 -yes numid=38 Simple mixer control 'Headphone',0 -err Simple mixer control 'PCM',0 -err mute not implemented Simple mixer control 'Front',0 -yes numid=19 Simple mixer control 'Front Mic',0 -err Simple mixer control 'Front Mic Boost',0 -err Simple mixer control 'Surround',0 -yes numid=3 Simple mixer control 'Center',0 -yes numid=5 Simple mixer control 'LFE',0 -yes numid=6 Simple mixer control 'Side',0 -yes numid=9 Simple mixer control 'Line',0 -yes numid=14 -- the best/ but no sound Simple mixer control 'CD',0 -yes numid=12 Simple mixer control 'Mic',0 -err Simple mixer control 'Mic Boost',0 -err Simple mixer control 'IEC958',0 -err Simple mixer control 'IEC958 Default PCM',0 -err Simple mixer control 'PC Speaker',0 -yes numid=22 Simple mixer control 'Capture',0 -err Simple mixer control 'Capture',1 -err Simple mixer control 'Channel Mode',0 -err Simple mixer control 'Input Source',0 -err Simple mixer control 'Input Source',1 -err I then tried each simple mixer control with tvtime. ]$ tvtime --mixer=hw0:'Control Name' returned mixer: attach error: No such file or directory mixer: Can't open mixer hw0:Line, mixer volume and mute unavailable. mixer: Can't open device hw0, mixer volume and mute unavailable. I then opened Advance Volume Control; set everyone of the controls listed by amixer scontrols to unmute 100% (see list above) and tried that. Next I tried each control individually or in combination according to its numid. ]$ tvtime --mixer=default/'Control Name' opened tvtime and made the volume keyes (+/-) functional. This is the opposite of what happened with PulseAudio installed. On the list above, I have marked each 'Control Name' with a -yes if no error was returned and -err if there was an error. See example below. $ tvtime --mixer=default/Speaker Running tvtime 1.0.2. Reading configuration from /etc/tvtime/tvtime.xml Reading configuration from /home/bill/.tvtime/tvtime.xml mixer: find error: Success mixer: Can't open mixer default, mixer volume and mute unavailable. mixer: Can't open device default/Speaker, mixer volume and mute unavailable.

'Splain please re: mixer, alsa, pulseaudio and tvtime??
Hi; My problem is not yet with tvtime but my question trail starts there. tvtime has been upgraded to use alsa for sound rather than OSS. To do that I need to re-set option name=MixerDevice value=default/Line/ to something like mixer=DEVICE[:CH] e.g hw:0/CD; where DEVICE = hw:0 and [:CH] = /CD. ls /dev/mixer no longer exists. Where does tvtime find DEVICE and where do I find DEVICE? How do I know it is the new name of the mixer? Which channel [:CH] do I use? Is it from the same list as tvtime.xml suggests for OSS or is it a different list? Given that I have an internal sound card on a PCIe bus how would I go about deducing which channels to try first? Now that I have the latest kernel and tvtime upgrade, these questions are so that I can overcome the confusion of many, many hours of experimentation and reading of outdated google comments. Hopefully, if I can solve tvtime or at least be looking at the correct configuration I can go on to solve problems with RhythmBox and others. A bit of a rant: The biggest problem that I have, and that others have mentioned they have, is the lack of trustworthy documentation -- something that starts with the real basics, on how alsa, pulseaudio, and the various guis work. -- Regards Bill Fedora 11, Gnome 2.26.3 Evo.2.26.3, Emacs 22.3.1 -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

You use it in digital mode not analogue, right? Then afais you need some software to play back audio instead of just a mixer to turn on a channel. How far have you come with using tvtime for /dev/video0 (as only the channel chooser) and mplayer for playing the mpeg stream on /dev/video1? Hopefully, if I can solve tvtime or at least be looking at the correct configuration I can go on to solve problems with RhythmBox and others. Audio playback problems in Rhythmbox? It's not so clever to mix too many problems. Audio in Rhythmbox and audio in tvtime are *very* different.

Thanks for responding Michael; I am trying to double check things before getting back to the bug. I am trying to secure myself from stupidity or at least ignorance.

You may want to run man amixer for a full explanation. amixer info - provides information about the default card. --- amixer scontrols - provides names of the controls for choice a. Simple mixer control 'Line',0 would be channel Line --- amixer scontrols - provides names of the controls for the f amixer controls - provides number/description for choice b. numid=19,iface=MIXER,name='Line Playback Volume' would be channel 19. --- amixer contents - gives much more information about the controls and the type of settings. It may help decide what control to use. --- aplay -l - lists the audio output cards in the system. Now, amixer defaults to sound card 0 (hw:0), but it can show other sound cards using the -c option (-c n). If your TV card is like mine, and has a external cable between it and the sound card, then you are probably going to be using someting like the Line channel. On the other hand, you probably also have controls on your TV card as well. For me it is sound card 1, but I normally leave the controls at max. I also have a mixer page for it in the Gnome mixer. Both amixer and aplay are part of the ALSA package.

Although I have read 'man amixer' in the past, in conjunction with your explanations, it now makes more sense. amixer info - provides information about the default card. ]$ amixer info Card default 'pulse'/'PulseAudio' Mixer name: 'PulseAudio' Components: '' Controls : 4 Simple ctrls : 2 I tried all 4 of the control names over a month ago and got no sound from using any of them with alsamixer and/or Advanced Volume Control [Device: HDA Intel (AlsaMixer)]. see below. --- amixer scontrols - provides names of the controls for choice a. Simple mixer control 'Line',0 would be channel Line $ amixer scontrols Simple mixer control 'Master',0 Simple mixer control 'Capture',0 --- amixer scontrols - provides names of the controls for the f amixer controls - provides number/description for choice b. numid=19,iface=MIXER,name='Line Playback Volume' would be channel 19. ]$ amixer controls numid=4,iface=MIXER,name='Master Playback Switch' numid=3,iface=MIXER,name='Master Playback Volume' numid=2,iface=MIXER,name='Capture Switch' numid=1,iface=MIXER,name='Capture Volume' Set ]$ tvtime --mixer=hw:0/Master Tried Advanced Volume Control set to [Device: Playback: Internal Audio (PulseAudio Mixer)] which showed only the 'Master' slider. TVTime had no sound. But at least responded visually to the +/- sound keys. However volume setting returned to 0 on each restart. Set tvtime --mixer=hw:0/Front Tried Advanced Volume Control set to [Device: Playback: Internal Audio (PulseAudio Mixer)] Got no sound, but did get the volume settings retained for each start. I then tried the pavucontrol gui configured to 'Profile: Output Analog Stereo + Input Analog Stereo'. The other options I had in the drop down list were various combinations of Input, Output; Stereo, Surround; Analog, Digital and IEC958. The Profile I choose, 'Output Analog Stereo + Input Analog Stereo', gave me the most detail under the Playback, Output Devices and Input Devices tabs. In fact, when using RhythmBox, Playback and Output Devices tabs showed the application name and a sound activity bar. Similarly, when playing a video on CNN, Playback showed 'ALSA plug-in [firefox]' and sound activity. However, when using tvtime no application is recognized by pavucontrol. Except that under the Input Devices tab, the sound activity bar jiggles a bit, as if trying to come to life. --- amixer contents - gives much more information about the controls and the type of settings. It may help decide what control to use. $ amixer contents numid=4,iface=MIXER,name='Master Playback Switch' ; type=BOOLEAN,access=rw--,values=1 : values=on numid=3,iface=MIXER,name='Master Playback Volume' ; type=INTEGER,access=rw--,values=2,min=0,max=65536,step=1 :
