Hello Takashi,Johan My patches are unessesary since following last patch was applied to the git: ALSA: usb-audio: Change internal PCM order
Capture working but there are no volume sliders for Line-In Capture or Mic-In Capture (I can only toggle on off). Probably the RANGES are broken?. From ASUS Windows driver I can see following ranges:
Master Volume: (Phisycal Knob on Asus) from 100 to 1 correspond 0dB to -70dB, 0 is -127dB Range from 1 to 100 -> 0dB to -70dB (logarythmic)
Mic-In: from 100 to 1 correspond 30dB to -10dB, 0 is -192dB Range from 1 to 10 -> -10dB to 10dB (linear?) Range from 11 to 100 -> 10dB to 30dB (logarythmic)
Line-In: from 100 to 1 correspond 0dB to -40dB, 0 is -192dB Range from 11 to 100 -> 10dB to 30dB (logarythmic)
Actual Situation: Input Gain Pad Control - 3 steps [0 - 50 - 100] Double Slider. In Capture and Playback Categories, both of them are controlled in the same time. Controls Playback Volume only, Capture not.
"Mic" and "Line" Switches [on/off] PCM Cature Source [Line/Mic] Electret Mic doesn't work. With all possible configurations - Silent. When I pluged Line level signal, I can record the signal without problems. PCM Capture Source [Line] - Line [on] Mic [off] - Sound PCM Capture Source [Line] - Line [on] Mic [on] - Sound PCM Capture Source [Line] - Line [off] Mic [off] - No Sound PCM Capture Source [Line] - Line [off] Mic [on] - No Sound The same with selected [Mic]. There is no Capture Volume control.
PCM 1 [mute/on] I think this is SPDIF switch. It doesn't work. When I switch it on -> Blue Led on Xonar doesn't light up.
I attached screen of alsamixer, usbmix from proc and my mixer_map from my old patch. I think there are is still bugs in parsing. Please point me how I can add manually Volume control for Capture?

Hello, This is my first patch to alsa-devel, and I'm not very skilled programmer. From lsusb -vvv, I've draw Xonar U7 map with all IT OT FU CS in mixer_map.c I don't know why the driver by default doesn't parse all info correctly. With this patch you can see Line Switch and Mic Switch in alsamixer. I can record my voice in Audacity with all supported bit and sampling rates in Mono or Stereo This is temporary solution. Please correct me if the patch is not properly made.
What doesn't work: - Cannot change Capture Volume for Line/Mic. No mixer control inalsamixer - Switching between Line/Mic doesn't work (Mute doesn't work) - SPDIF not tested As what I wrote at beginning I'm not skilled programmer so any help is aprreciated
proc-usbmixer -> cat /proc/asound/*/usbmix usb.debug -> lsusb -vv (only Asus Xonar U7)
The changes in mixer_maps.c look good, but what's the reason for uac2_audio_feature_info[]? It seems adding "Control" suffix to each entry, which doesn't look correct.
thanks,
Takashi
