Created attachment 863008 [details] pulseaudio -vvvvv I killed and restarted pulseaudio per https://fedoraproject.org/wiki/How_to_debug_PulseAudio_problems and fiddled a bit with audio volume, settings, audio tests in settings, finally detaching it because it's too loud; test audio is reproduced from the audio/video system settings but I could not get the applications to reproduce audio again though, the KDE mixer also thinks there's no audio device available. Will probably have to reboot I guess, as the first time I configured it. your alsa-info did not contain any info of your USB audio do you need to specify index for your USB audio and your two hda intel cards ? post the output of alsa-info.sh for your USB audio which contain min , Max , dbmin and dbmax of the volume controls of your USB audio D: [pulseaudio] alsa-mixer.c: Path analog-output (Uscita analogica), direction=1, priority=99, probed=yes, supported=yes, has_mute=yes, has_volume=yes, has_dB=yes, min_volume=0, max_volume=9472, min_dB=-37, max_dB=0 D: [pulseaudio] alsa-mixer.c: Element PCM, direction=1, switch=1, volume=1, volume_limit=-1, enumeration=0, required=0, required_any=0, required_absent=0, mask=0x3600000000f66, n_channels=2, override_map=yes I: [pulseaudio] alsa-sink.c: Hardware volume ranges from -37,00 dB to 0,00 dB.

Sorry, this one should contain it.

what about the range bewteen 0% and 24% ? as min dB is -37dB

9472 = 37 * 256 but is not a multiple three and you cannot use cval->res = 384 https://git.kernel.org/cgit/linux/kernel/git/tiwai/sound.git/commit/sound/usb/mixer.c?id=bc3a8a01def4fb0ec0ef8a20d097277b9c6b2a1f you have to find out the value of cval->res if you think the volume control cannot provide a resolution of 1/256 dB Thanks. I begin to understand. How would I change the value of cval->res for testing what's the best value and reporting back? as 37 is a prime number, this mean that the possible resolution can only be 1, 0.5, 0.25, ..... 1/128, 1/256 dB Simple mixer control 'PCM',0 Capabilities: pvolume pswitch pswitch-joined Playback channels: Front Left - Front Right Limits: Playback 0 - 9472 Mono: Front Left: Playback 6270 [66%] [-12.51dB] [on] Front Right: Playback 6270 [66%] [-12.51dB] [on] speaker-test -D hw:0,0 -c2 -t sine you can use amixer -c0 set value,value value from 9472 and decrease value until you notice the volume really changed by hearing or record using audacity and check the record signal drop visually I've not understood how to use amixer as you say, sorry (it asks some further parameters); but I opened alsamixer and changing values didn't affect anything initially, however after F6: Select sound card -> 2 Audio Advantage MicroII I could tweak volume again. The lowest volume at which I hear something is 2 %, PCM [dB gain: -35,46, -35,46], while I hear nothing at 1 %, PCM [dB gain: -36,25, -36,25]. That is, nothing but the loud buzz which is constant when powered up. Items S/PDIF and Loudness are muted (MM). Found it. The audio is enabled starting at value 256 (amixer -c 2 set PCM 256). http://www.freedesktop.org/wiki/Software/PulseAudio/Backends/ALSA/Decibel/ pulseaudio expect the volume really change by 1/256 dB per step but in practice the volume is only changed after you adjust the value for cval->res steps I've read that page once again, thank you very much for your heelp and patience, but I don't understand if there's anything concrete that I can/should still do here. Unless a configuration can fix this I'm going to return the speaker this week and I won't be able to test further. I've a USB speaker based on this chipset and see exactly the same error message. Using rawhide, but I can also test F19, F20, all with same symptoms. kernel-3.15.0-0.rc8.git1.2.fc21.x86_64 pulseaudio-5.0-4.fc21.x86_64 This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'.
