Please correct me if I'm wrong. The "EQ Peaks" Simple Mixer Element has more channels than the 9 channels described in the snd_mixer_selem_channel_id_t enum. ( SND_MIXER_SCHN_FRONT_LEFT up to SND_MIXER_SCHN_REAR_CENTER ). http://www.alsa-project.org/alsa-doc/alsa-lib/group___simple_mixer.html#g9cb8437b2f92d168c43e4da2c667e823 Alsamixer-Qt4 currently can only show these 9 channels - in the channels mixer dialog - which is not sufficient. I did not find a function like snd_mixer_selem_playback_channels which would return the number of channels. So to find out how many channels there actually are I would have to do something like this int num_playback = 0; for ( int ii=0; ii < 1024; ++ii ) { if ( snd_mixer_selem_has_playback_channel ( elem, ii ) ) { num_playback += 1; } else { break; } } > 2) CMI8788 's 8 Channels Master Volume Control > > https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4204 > > Card hw:0 'CMI8788'/'C-Media Oxygen HD Audio (rev 2) at 0xec00, irq 17' > > Mixer name : 'CMI8788' > Components : 'AK4396 AK5385 CMI8788' > Controls : 23 > Simple ctrls : 12 > Simple mixer control 'Master',0 > Capabilities: pvolume pswitch pswitch-joined > Playback channels: Front Left - Front Right - Rear Left - Rear Right > - Front Center - Woofer - Side Left - Side Right > Limits: Playback 0 - 255 > Mono: > Front Left: Playback 112 [44%] [-7.14dB] [on] > Front Right: Playback 112 [44%] [-7.14dB] [on] > Rear Left: Playback 178 [70%] [-3.12dB] [on] > Rear Right: Playback 178 [70%] [-3.12dB] [on] > Front Center: Playback 178 [70%] [-3.12dB] [on] > Woofer: Playback 178 [70%] [-3.12dB] [on] > Side Left: Playback 178 [70%] [-3.12dB] [on] > Side Right: Playback 178 [70%] [-3.12dB] [on] > > > state.CMI8788 { > control.1 { > comment.access 'read write' > comment.type INTEGER > comment.count 8 > comment.range '0 - 255' > comment.dbmin -9999999 > comment.dbmax 0 > iface MIXER > name 'Master Playback Volume' > value.0 112 > value.1 112 > value.2 178 > value.3 178 > value.4 178 > value.5 178 > value.6 178 > value.7 178 > } Basically the same issue?
