One of the machines has ALC255 on it, another one has ALC298 on it. On the machine with the codec ALC298, it also has the speaker volume problem, so we add the fixup chained to ALC298_FIXUP_SPK_VOLUME rather than adding a group of pin definition in the pin quirk table, since the speak volume problem does not happen on other machines yet.

commit 59ec4b57bcaede46546d54d037a21004b9aa5cef upstream.

One of the machines has ALC255 on it, another one has ALC298 on it.

On the machine with the codec ALC298, it also has the speaker volume
problem, so we add the fixup chained to ALC298_FIXUP_SPK_VOLUME rather
than adding a group of pin definition in the pin quirk table, since
the speak volume problem does not happen on other machines yet.

ALSA: hda/realtek - Can't adjust speaker's volume on a Dell AIO 2016-08-20T16:09:24+00:00 Hui Wang hui.wang@canonical.com 2016-08-01T02:20:32+00:00 39d505450f84aef77377c1fe0757e6b906132112 commit dd9aa335c88003d131ac874e7f6809902de0b847 upstream. We have a Dell AIO on which we can't adjust its speaker's volume. The problem is it is connected to a Audio Output node without Amp-out capability. To fix it, we change it to be connnected to a node with Amp-out capability.

It's superfluous when done during the device got disconnected. Although the notification itself is mostly harmless, it may potentially be harmful, and should be suppressed. Actually some components PCM may free ctl elements during the disconnect or free callbacks, thus it's no theoretical issue.
