Package: alsa-utils Version: 1.1.6-1 Severity: normal Dear Maintainer,
To give some background I have a TV card whose line-out is connected to sound card line-in. As far as I can tell for Debian Testing = Buster line-in for this sound chip (and possibly all others although I can find no documentation of this) only gets connected to *sound card* line-out and therefore to my computer speakers if alsamixer the Loopback item for this sound chip is enabled. (This is the only way I have been able to hear the audio channel of the TV card.) In my prior experience with Debian Oldstable = Jessie, I don't recall there was an alsamixer Loopback item to be enabled, but the net effect for that version of Debian was sound card line-in was automatically connected to sound card line-out. And in that Oldstable case the volume of TV audio results could be controlled from both Line and Master. The issue for the present Debian Buster case is the volume of the TV results can only be controlled by Line which means generic volume controls (e.g., from the pulseaudio "sound card" that alsamixer sees) whose Master item interacts with the Master item of the Realtek ALC887-VD sound card have no effect on the volume of the TV results. Which in turn means that tvtime, for example, cannot control the volume of the TV any more. I don't have a clear picture about how the Master item controls the overall volume associated with most alsamixer items for the Realtek ALC887-VD, but the fix for the current bug should be that Master control is also extended to the alsamixer Line item for that sound card. -- System Information: Debian Release: buster/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.18.0-1-amd64 (SMP w/16 CPU cores) Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8), LANGUAGE=en_CA:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages alsa-utils depends on: ii kmod 25-1 ii libasound2 1.1.6-1 ii libc6 2.27-6 ii libfftw3-single3 3.3.8-2 ii libncursesw6 6.1+20180714-1 ii libsamplerate0 0.1.9-2 ii libtinfo6 6.1+20180714-1 ii lsb-base 9.20170808 ii whiptail 0.52.20-7 alsa-utils recommends no packages. alsa-utils suggests no packages. -- no debconf information
