alsa-utils: 1.0.29 -> 1.1.0
Changelog: http://alsa-project.org/main/index.php/Changes_v1.0.29_v1.1.0 This release introduces two new tools: - alsatplg for converting topology data from text representation to a binary format consumed by the kernel - alsabat; "bat" stands for "basic audio tester" Backported a patch from upstream that renames bat to alsabat. Rebased patch "0001-alsactl-don-t-let-systemd-unit-restore-the-volume-wh.patch". Dropped patches "alsa-utils-aplay-interrupt-signal-handling.patch" and "assume-storing-is-success-if-not-sound-card-device.patch", because the issues have been fixed upstream.

5
6alsa-utils as well as bareos-bat (as well a some Bacula packages)
7all contain a program called /usr/bin/bat, which causes conflicts on
8various distributions ("basic audio tester" vs "bareos administration
9tool"("bacula administration tool")).

1[PATCH] assume storing is success if not sound card device
2
3Upstream-Status: Pending
4
5Systemd will report failure when run alsa-*, if the machine has not the
6sound card. To void this annoyed message, alsa-restore/alsa-state ignore
7all the exit codes by prefixing "-" in ExecStart, like:
8
9 alsa-utils-1.0.29$ grep "=-" ./ -r|grep service.in
10 ./alsactl/alsa-restore.service.in:ExecStart=-@sbindir@/alsactl restore
11 ./alsactl/alsa-state.service.in:ExecStart=-@sbindir@/alsactl -s -n 19 -c rdaemon
12 ./alsactl/alsa-state.service.in:ExecStop=-@sbindir@/alsactl -s kill save_and_quit
13 lsa-utils-1.0.29$
14
15But alsa-store.service.in is missing, and better solution is to ignore
16the exit code 19 which means not sound card device, not all exit code
