testing/selftests/alsa/mixer-test: 10 failures on Dell XPS 13 9360

Dear Linux folks,

Running the ALSA kselftests with Linux 6.10-rc1, `mixer-test` shows ten failures:

# Totals: pass:24 fail:0 xfail:0 xpass:0 skip:11 error:0

These are:

not ok 5 write_invalid.0.40 not ok 11 write_valid.0.39 not ok 18 write_valid.0.38 not ok 25 write_valid.0.37 not ok 201 write_invalid.0.12 not ok 208 write_invalid.0.11 not ok 264 write_invalid.0.3 not ok 271 write_invalid.0.2 not ok 278 write_invalid.0.1 not ok 285 write_invalid.0.0

`./pcm-test` finishes with 5 out of 5 passes.

The output `sudo alsa-info` is uploaded to the database [1], and the full output of `mixer-test` is attached.

Kind regards,

Paul
